Version: unspecified (using KDE 4.4.2) OS: Linux With composite enabled, when I maximise a window, a 1 pixel line of the desktop background is visible between the panel and the window. When I disable composite, that line is coloured in the background colour of the panel, so that it is perceived as part of the panel. Reproducible: Always Steps to Reproduce: Just enable compositing and maximize a window. The effect might be hard to notice on some desktop backgrounds though. Actual Results: The window is one pixel too narrow in height, leaving one pixel of desktop background visible (or the panel reports its height one pixel too high). I attached a screenshot showing the effect: The left half has compositing disabled, the right one has it enabled. You can clearly see the black line which is coming from the desktop background. Expected Results: The lowest window pixel should be directly above the panel. OS: Linux (x86_64) release 2.6.32-24-generic Compiler: cc I am using the default Plasma style.
Created attachment 49782 [details] A screenshot showing the issue (right half is with composite, left half without)
attaching plasma since this is (if not intended) likely a panel bug (mismatch between the set and the visual strut)
