Double rebooting required after upgrades for months
For weeks or months I have a weird, though not serious, issue:
After an upgrade, if I launch "mpv" (fork of mplayer), it breaks my system:
it stops displaying windows decorations, I cannot switch between windows
However I still have access to the panel, I still can logout or reboot.
I don't know if the issue is systematic: I have this issue for months (I
thought it was linked to the issue with xorgs which happened some weeks ago;
obviously it's unrelated); but this issue is always transient and never
persists after a second reboot.
There might have been other glitches occurring after upgrade-single-reboot,
like Knote's notes vanishing and then reappearing...
I'm wondering what mechanism can differentiate double reboot from single one.
