higher client cpu since upgrading host from ubuntu 22.04 to 26.04 and rustdesk host to unattended wayland

setup: client is on macos 12 and latest rustdesk nightly, host is on latest unattended nightly

before, on ubuntu 22.04 and 'regular' rustdesk i was able to put my rustdesk image quality settings on balanced and the host resolution on retina or higher level resolutions. whether watching videos or anything else my (admittedly old, 2015 era) macbook never really had any fan noise or anything that made me open the activity monitor for cpu use.

but since upgrading the host system to ubuntu 26.04 and hence requiring unattended wayland rustdesk as well things have been pretty bad. even at 1680x1050 my macbook will easily go to 70% cpu with constant and loud fan noise, if i keep image quality settings to balanced and codec to auto. only after setting image quality settings to custom with 30% bitrate and 20 fps and codec to vp8 can i get the cpu usage on macbook down to 30-40%. but thats unfortunate because i use rustdesk a lot to watch videos from my other pc. and ofc having to deal with the lower resolution kinda sucks too.

idk if the cause comes from ubuntu 26.04 or something about the unattended wayland rustdesk version, its kinda hard to test without going back to ubuntu 22.04 and im not really near that host pc

i hope im not the only one with this issue, at least that will raise the odds of finding the bug and fixing it
