Description Trevor Spiteri 2002-06-19 09:23:40 UTC 
If metacity is not fast enough, e.g. because of momentarily busy (as in
thrashing) system, just tapping the keys to cycle windows (pressing them
and releasing them fast enough) results in the tab popup remaining there.

To reproduce easily, run metacity on gdb, and put a breakpoint at the
beginning of the handle_tab_forward() function in keybindings.c. Pressing
Alt Tab to cycle the windows triggers the breakpoint. Continuing metacity
on gdb results in the reported behaviour.

Problem is that we only get the Alt key release if we establish a grab
prior to the key being released. Otherwise we miss the Alt release.

I'm not sure how to fix this yet. We can't really passive grab plain 
"Alt" keypresses, I don't think.
Comment 2 Havoc Pennington 2002-09-24 19:18:30 UTC 
Owen do you have any ideas on this race? Should I passive grab the 
key bound to the Mod1 modifier?
Comment 3 Owen Taylor 2002-09-24 19:33:47 UTC 
Well, cheesy solution is to check if the Alt key is still
down after you make your grab, if not, abort immediately.
Comment 4 Heath Harrelson 2002-10-30 15:45:26 UTC 
Batch adding GNOME2 keyword to Metacity bugs.  Sorry for the spam.

This also appears to happen when switching workspaces via C-A-arrow_key
