Description Tobot 2003-04-24 02:25:43 UTC

Version:            (using KDE KDE 3.1.1)
Installed from:    Compiled From Sources
OS:          Linux

After pressing alt-tab and holding down alt, the little window pops up with the icons on it. Every time I press 'tab' after this, all of the icons are redrawn. This causes any icon with alpha transparency to darken as the alpha "sees" the already-drawn icon behind it. After tabbing for a while, shadows turn completely black. This is noticeable with konsole's smallest icons.

Can you provide a screenshot of it (ksnapshot with timeout should handle it). The icons in 
Alt+Tab box AFAIK don't have any alpha, they only have a mask, and in such case there can't 
be the described problem.

OK. Here is before (just after hitting alt tab) and after (after holding down
tab for a few seconds). Note that the shadows behind the konsole have gotten
really dark.

Really, strange, I never noticed.
