I have latest update of Fedora 33 (both rpm-ostree upgrade and flatpak update), but occured also with older versions. First I thought it happens only with Firefox, but it seems to happen with other programs as well.
When exiting a program in GNOME, it is not shown anymore. But, the process still exists.I googled for such a behavior, but haven’t found anything. Restarting is not possible, since the process still exists.
I think that following might be related: Sometimes when opening new Firefox’s windows, it take up to several minutes, until a new window is shown.
Do you have encounter similar problems?
(I haven’t found a similar bug report…but may have search for wrong key words?)
