Version: (using KDE 4.2.85) OS: Linux Installed from: SuSE RPMs With "desktop effects" turned on window resizing becomes painfully slow. I have 30-100fps during normal usage but when I resize a window this drops to 1fps. I have not been able to identify a specific effect that is causing the problem. Hardware info: Thinkpad T60 ATI Radeon Mobility X1400 @ 1680x1050
You may try to disable "show content while resizing" setting. This should improve the situation. *** This bug has been marked as a duplicate of bug 191329 ***
