Description Daniel Andre Eikeland 2008-08-03 13:45:16 UTC 
Version:            (using KDE 4.1.0)
Installed from:    Ubuntu Packages
OS:                Linux

I have set up kwin to switch workspaces left and right with ALT+CTRL+LEFT / ALT+CTRL+RIGHT.
If i press this combination and "start" the desktop switching (which takes about one second), and at the same time press ALT+TAB, ALT+TAB works, but when I release it, the "ALT" key is frozen, which means I cannot use it anywhere, not even in other programs.

I can "unfreeze" it by triggering some other kwin function manually, such as moving my mouse pointer to the top-left corner, which triggers an "Expose" effect for all windows. After that has been done, the ALT-key is usable again.

Reproducability: ~90%, depending on how fast the desktop switching goes.
