When firefox is busy with a large download, system locks up after some hours (cpu is hot).
on an intel laptop:
xpra on F29 64 on i3 has <1% cpu
First, since you have two xpra processes, my guess is that you have speaker forwarding enabled and this will consume quite a bit of CPU.
Second, just because Firefox doesn't use much CPU does not mean that it isn't updating its window.
Try running the xpra server with the debug flag -d compress
to see if there are screen updates being sent.
Finally, please see wiki/ReportingBugs to provide more details so we can help you.
cat .xpra/xpra.conf speaker=off printing=off
Thanks, this brought CPU down, would never have thought, that sound is so expensive.
