I have a keyboard a4tech KV-300h and the bug reproduce on windows too. I have already tried to replace to another a new keyboard. The problem isn't gone. I found out if I use embedded USB port of keyboard to connect a mouse then the problem reproduce very often. Also I tested my keyboard on macbook pro. There is everything works fine.

For example when clicking Alt-F4, sometimes it gets stuck so all the windows are closed instead of just one. My configuration is Feisty + Xgl + Compiz Fusion. My previous configuration was Edgy + Xgl + Beryl, where this didn't happen. Others have reported the same problem without using either Xgl or Compiz. The keyboard itself isn't the problem. When dual-booting to Windows, everything works fine. Also, the problem happens with two different keyboards (internal laptop, external USB). My best guess is that the problem occurs at time of high system load. Somehow during these times the key-release signal gets lost and the key-press is repeated indefinitely. This happens more often with Compiz configurations because Compiz tends to increase system load. It also happens more often with power-hungry apps like Firefox and Acrobat Reader for similar reasons. PS: When the keys would repeat all input devices would be locked up. ie. mouse won't move, clicks don't do anything, keyboard presses don't register. Then when it becomes unstuck, the mouse moves around and everything. Hope this helps.
