Trying to write my slides using Impress under Wayland, but the GPU usage keeps going up to 99% and Impress becomes unresponsive.
We don't have any similar bug report, which means this is somehow related to your system or usage pattern... Are there concrete steps to get the hangout? Does it happen in a new presentation, or only with a template? Or when inserting an image? Does it happen in normal or outline mode?
If it is not specific to some usage pattern, it might help to get a backtrace: run
dnf debuginfo-install libreoffice-impress
as root to install debuginfo, then start impress, make it hang and run
pstack `pidof soffice.bin` > backtrace
and attach the file 'backtrace' here.
As a workaround, you can use the old gtk2 backend, which doesn't use Wayland. Ensure libreoffice-gtk2 is installed, then start libreoffice from terminal as
could log in under X too to see if its related to wayland and we're innocent or if it persists to rule that in or out
Closing this old bug as I can't reproduce anymore
I bet this was the bug in glib which triggered 100% cpu usage.
