--- Comment #34 from Sveinar Søpler <cybermax at dexter.no> ---
Can't say i have ever experienced this, but i do not use a DVI monitor. Mine is
DP on main, and HDMI on my second monitor.

Maybe it is some strange stuff with multi-monitors with one of them connected
to DVI? I get around 1.3-2% 1-core load when running regedit.

RTX2070. Currently 470.62.13 driver, but did not have this with 495.44 either.

If you wonder where that strange "falling back to randr 1.0" message comes
from:
https://github.com/wine-mirror/wine/commit/f5e6c086f91749e9e302c1abf858807535bc9775

Some of this is removed with the proton fshack patchset:
https://github.com/ValveSoftware/wine/commit/352b0304a357f9e062695c45ed12d74e0cfc70db

Not sure if it is related to this bug, but you mentioned the message.. and it
is logged in wine logs and (should) not in Xorg.0.log.
Perhaps try WINEDEBUG=-all,+xrandr ?

Normal log: 
0070:trace:xrandr:X11DRV_XRandR_Init Found XRandR 1.6.
