Hi there, I can confirm this bug. It wasn't appearing too often before, but it seems like it's happening frustratingly more often ever since I upgraded to 2.99.917 (running sid)
I can see no tangible error in syslog or xorg.log, maybe except for some lines that don't seem to be too precise about the nature of the issue: Jun 23 16:54:53 boohn gnome-session[1664]: ** (gnome-shell:1793): CRITICAL **: remove_mnemonics: assertion 'label != NULL' failed Jun 23 16:55:06 boohn gnome-session[1664]: (gnome-shell:1793): mutter-WARNING **: STACK_OP_ADD: window 0x1800368 already in stack I'm running a thinkpad x201. I can send more info about my setup if this can help. -- Gabriel Filion
