Crash on linux-mint 21/22

[giangbang]

Occasional crashes on both linux mint 21 and 22 (though I'm not sure what triggers it), here I attach the crash logs report from System Reports (link)

From this log, there seems to have Segmentation fault at Wnck::activate(GroupWindow*, unsigned int) (maybe null pointer? I do not see any safe check in that case).

I do not use multiple display devices, so #61 seems irrelevant,
