Probably blocking somewhere in plasma-pa. But it also seemes to me a case of dont do it then. I can't reproduce, please attach a backtrace of plasmashell when its frozen. (In reply to David Redondo from comment #2) > I can't reproduce, please attach a backtrace of plasmashell when its frozen. How do i make a backtrace ? type gdb -p $(pidof plasmashell) wait until you see the (gdb) prompt and type bt (In reply to David Redondo from comment #4) > type > > gdb -p $(pidof plasmashell) > > wait until you see the (gdb) prompt and type > > bt (gdb) bt #0 0x0000773969cb0892 in ???

() and i get it reliable reproduce with doing systemctl restart --user pipewire.service pipewire-pulse.service wireplumber.service pipewire.socket pipewire-pulse.socket and then right after click on play on a youtube video. Thanks I cannot immediately reproduce, looks like tear down of pipewire stuff I also cannot reproduce the issue on current git master, BTW. |
