Version: 4.0.0 (using KDE 4.0.0) Installed from: Ubuntu Packages OS: Linux With compositing enabled, I have some odd drawing problems when I mouse over, for example, the 'maximize' and 'minimize' buttons, or when I mouse over the borders of an inactive window. The part of outermost 1px of the border adjacent to where I'm mousing seems to get drawn incorrectly at these times.
I cannot reproduce. What gfx driver, does the problem remain if you try a different version of it?
Don't you think this bug and bug 155214 are related ? http://bugs.kde.org/show_bug.cgi?id=155214
