STEPS TO REPRODUCE 1. Run kolourpaint and maximize it vertically 2. Close kolourpaint 3. Start again kolourpaint. Height is equal to height of screen 4. Maximize it to full screen and unmaximize 5. Height of window is not equal to height of screen OBSERVED RESULT After first unmaximize kolourpaint window loses its height equal to height of screen. But if maximize it vertically again all next maximize/unmaximize works as expected. It affects only FIRST maximize/unmaximize. All above also valid for horizontal maximizing. First maximize/unmaximize changes initial width of window. Very annoying behavior. EXPECTED RESULT Height(or width) equal to height(or width) of screen should be preserved after first unmaximize as all next maximize/unmaximize.
It is same annoying behavior for horizontal maximizing. This is very old bug. It is exists many years. Someone can fix this?
