Keyboard keys such as the arrows, Alt-F4, PageUp/PageDown, etc. often get 'stuck' and continue being 'clicked' even after they are physically released. 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.

The Compiz Fusion folks said this is a well-known Xgl problem, but I couldn't find supporting evidence for that.

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).
