Unfortunately this didn't return anything. However I did find out that it's probably a pipewire bug, but I don't know why it would freeze the whole display. Today when it happened I SSH'd and ran `systemctl --user restart pipewire` and that completely unfreezed/fixed the display. I added an attachment with the journal output from the restart. Also before the restart I ran `sudo cat /proc/$(pidof kwin_wayland)/stack` and got: [<0>] futex_do_wait+0x4a/0x80 [<0>] __futex_wait+0x8e/0xf0 [<0>] futex_wait+0x78/0x120 [<0>] do_futex+0xc5/0x190 [<0>] __x64_sys_futex+0x12d/0x210 [<0>] do_syscall_64+0x81/0x7f0 [<0>] entry_SYSCALL_64_after_hwframe+0x76/0x7e Normally for this I get: [<0>] poll_schedule_timeout.constprop.0+0x37/0x90 [<0>] do_sys_poll+0x3fe/0x590 [<0>] __x64_sys_ppoll+0xdf/0x180 [<0>] do_syscall_64+0x81/0x7f0 [<0>] entry_SYSCALL_64_after_hwframe+0x76/0x7e -- You are receiving this mail because: You are watching all bug changes.
