This file lists known bugs in the 1.4.1_light release that are not
considered "release critical" and are difficult to fix:


1. Flicker when zooming in/out.

3. Tool Box & Colour Box RMB ToolBar Menus do not work.

4. Image dialog spinboxes should accept Enter Key (instead of the dialog's
   OK button) after the user has typed something.

      OR

   Spinboxes should signal that their values have changed every time the
   user changes the text (rather than after pressing Enter or clicking on
   another spinbox etc.).

   The need for the "Update Preview" button and the difficulty of keeping
   the percentages and dimensions in sync in the Resize / Scale dialog are
   manifestations of the current QSpinBox behaviour.

6. a) The undo history and document modified state are not updated during
      the drawing of multi-segment shapes (Polygon, Connected Lines,
      Curve).  They are however updated after shapes' completion.

   b) The text and brush-like tools set the document modified flag even if
      user cancels the draw operation.

   c) Select a region, manipulate it (e.g. move), undo - the document is
      still marked as modified (because 2 commands - the create selection
      and the move - were added but only one was undone).

7. Certain shapes may have the wrong size (usually only a pixel off and
   only in extreme cases) e.g. an ellipse of height 1 always has a width 1
   pixel less than it should be.  This is a Qt bug.

8. At zoom levels that aren't multiples of 100%, parts of the image may
   appear to move when the user interacts with it.  Other minor redraw
   glitches may also occur at such zoom levels.

9. Keyboard shortcut changes do not propagate to other KolourPaint windows
   (but will propagate to future windows).

10. "File/Open Recent" entries are not updated interprocess.

11. The blinking text cursor will "disappear" if you type more text than
    you can fit in a text box.

12. You cannot select only parts of the text you write.

13. Due to a workaround for a Qt bug, writing text with the foreground
    colour set to transparent is incredibly slow.  Write your text in
    another colour and then set the foreground colour to transparent after
    you've finished typing to avoid this issue.

14. The text cursor may be momentarily misrendered when scrolling the view.

16. The Edit/Paste option is not disabled when the clipboard data is lost
    due to the owner terminating (no QClipboard::dataChanged() signal).

17. a) Using KolourPaint on a remote X display may result in redraw errors
       and pixel data corruption.

    b) KolourPaint is screen depth dependent.  Opening an image with a
       an alpha channel and/or a depth higher than the screen and then
       saving it will likely result in loss of colour information.  To
       reduce data loss, run your screen at 24-bit.  This bug will be
       addressed in a future version of KolourPaint.

19. Read support for EPS files is extremely slow.  You should not enable
    the "Save Preview" dialog when saving to EPS.  This is an issue with
    KDE.

20. Pasting a large image (esp. one that doesn't compress well as PNG)
    into an image editor (not necessarily KolourPaint) running as
    different process from the KolourPaint which was the source of the
    image, on a sufficiently slow computer, may fail with the following
    output to STDERR:

      "kolourpaint: ERROR: kpMainWindow::paste() with sel without pixmap
       QClipboard: timed out while sending data"

    This is a Qt bug.

21. It is not always possible to copy and paste between 2 instances of
    KolourPaint running different Qt versions.  See
    QDataStream::setVersion().

22. The Emboss, Blur and Sharpen effects give different results depending
    on _both_:

    a) The KDE version KolourPaint was compiled with
       (due to KImageEffect not supporting strength settings for these
        effects in KDE 3.0, KolourPaint repeats these effects in order to
        simulate strength)

    b) The KDE version KolourPaint is running under
       (e.g. for the same function calls, KDE 3.2's effects are slower but
        give better results than those in KDE 3.0)

23. Changing tool options while in the middle of a drawing option may
    confuse KolourPaint.  For instance:

    a) With the brush tools, the cursor incorrectly appears.

    b) With the rectangle-based tools, the temporary pixmap does not resize
       when the line width increases.

24. In transparent background mode, the Text Tool does not antialias.

25. Sometimes when you take a screenshot of a window, and then paste in a
    new window, it will be greyscale.  When pasting again, it will still be
    greyscale.  Cannot consistently reproduce.  [Thurston]


Issue with XFree86 <= 3.3.6 with the "Emulate3Buttons" Option
=============================================================

When drawing, clicking the left or right mouse button that did not
initiate the current operation will, in this order:

1. finalise the current drawing operation
2. attempt to paste the contents of the middle-mouse-button clipboard

instead of canceling the current drawing operation.

This is due to XFree86 sending a release notification for the button that
initiated the drawing operation, followed by a press notification for the
emulated 3rd button; instead of just a single press notification for the
button that is intended to cancel the operation.  This works correctly in
XFree86 4.x with "Emulate3Buttons" on because it is harder to trigger the
emulation for the 3rd button as it is only invoked if the left and right
buttons are pressed at almost the same time.

Possible solutions:

a) Use XFree86 4.x or an X server from another vendor (e.g. X.org).
b) Press Escape in KolourPaint to cancel the current drawing operation
   instead of using the problematic click method described above.
c) Disable "Emulate3Buttons".


---------------------------------------------------------------------------
The following info does _not_ apply to CVS HEAD nor KDE 3.4.  This version
of KolourPaint won't even compile on KDE < 3.3.  This info is only here so
that I won't forget to include it in backport branches of KolourPaint.
---------------------------------------------------------------------------


Issues with Early Versions of KDE 3.x and Qt 3.x
================================================

KolourPaint 1.4.1_light runs best on KDE 3.4 and Qt 3.3.  It will compile
and run on earlier KDE and Qt 3.x releases but you may encounter the
problems listed below.


[COMPILE-TIME] - Means that this problem will be caused by compiling
                 against an early Qt and/or KDE.  Recompiling KolourPaint
                 against newer libraries is the solution.
[RUNTIME] - Means that this problem will be caused by running under an
            early Qt and/or KDE.  Upgrading those libraries will solve this
            problem.  There is no need to recompile KolourPaint.


KDE = 3.0
---------

1. [COMPILE-TIME]
   Due to the lack of KImageIO::typeForMime(), KolourPaint can only support
   a limited number of output formats (you'll only notice this if you have
   more KImageIO formats than a standard KDE 3._3_ install).

3. [COMPILE-TIME]
   The keyboard modifiers may get out of sync with reality in certain
   corner cases.

4. [COMPILE-TIME]
   The "Settings / Toolbars" submenu is not available.

6. [COMPILE-TIME] (yes, the number is out of order)
   The widget for selecting saving options in the file dialog does not line
   up with the "Location" and "Filter" combo boxes.

5. [COMPILE-TIME]
   The "Settings / Configure Toolbars..." menu item is not available.  This
   is to protect you from destroying all the standard actions in the Main
   Toolbar due to action merging not working for toolbars.

2. [RUNTIME] (yes, the number is out of order)
   The Resize / Scale Dialog's percentage input fields are missing the
   spinbox arrows.


KDE = 3.1
---------

1. [RUNTIME]
   The Tool Box buttons are not clearly rendered in early versions of the
   Keramik style (such as the one included in KDE 3.1).  It may be hard to
   see what tool is currently selected.  Either upgrade to KDE >= 3.2 or
   use another style such as HighColor Classic or Plastik.


KDE <= 3.1
----------

2. [COMPILE-TIME]
   The "Settings / Show Statusbar" menu item is not available.

3. [COMPILE-TIME]
   The filedialog filter combobox is editable as part of a workaround for a
   Qt bug (which normally causes a filedialog destruction crash).

4. [COMPILE-TIME]
   Alpha channel checks will be performed when opening and pasting images
   even if the appropriate "Do not show this message again" checkbox has
   been ticked (i.e. slower).  Unwanted notifications of low screen depth
   and alpha channel may also be given.

5. [COMPILE-TIME]
   The "Settings / Full Screen Mode" menu item is not available.


KDE <= 3.2
----------

1. [RUNTIME]
   Some images (usually small ones) are incorrectly positioned and may be
   cut off when saving in the EPS format.

2. [RUNTIME]
   Support for the formats:

      * Truevision Targa Image
      * Portable Graymap Image
      * Portable Pixmap Image

   is very buggy and should not be considered as working at all.

3. [RUNTIME]
   Moving the mouse over the drawing area takes an unnecessarily large
   amount of CPU due to unneeded status bar updates.


Qt <= 3.2
---------

1. [COMPILE-TIME]
   The thumbnail will flicker near or above the toolbars before appearing
   in its rightful place.
