This file lists known bugs in this version 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.

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.  Also,
       8-bit screens are not supported at all.  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.

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 has not been tested at zoom levels other than 100%.

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


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".
