Please send bug reports and feature requests to http://bugs.kde.org/.
Don't hesitate to report bugs nor hesitate to send us your wishes - it
provides valuable feedback that will help to improve future versions of
KolourPaint and you will not receive flames for reporting duplicates.


This file lists known bugs in this version that are not considered
"release critical" and are difficult to fix:


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.

   Update: Text input is broken in KDE4.

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 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).  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.

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

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

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().

23. Changing tool options while in the middle of a drawing option should
    work but confuses KolourPaint instead.  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.

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]

26. Drawing with the keyboard is unreliable.  Depending on the X server,
    either holding down Enter may continually switch between drawing and
    not drawing or KolourPaint may fail to detect the release of the Enter
    key.

27. InputMethod had not been tested at zoom levels other than 100%.

28. KolourPaint has not been tested against invalid or malicious clipboard
    data.

29. The Tool Box and Color Tool Bar are no longer movable or floatable.

30. The "Skew", "Rotate" and "Smooth Scale" effects produce low quality
    results.

31. The rendering quality of a text box with opaque text but a see-through
    background, on top of transparent document areas, is lower than in KDE 3
    versions of KolourPaint.


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".
