Environment:

Ubuntu 20.04 LTS 64bit
GPU: NVidia RTX2080
GPU Driver version: 470.86
Screen: two screens: the one built-in is 1920x1080, and the other external is 2K (2560x1440)
Wine HQ: 7.0
Windows program: winecfg.exe

When start it show bellow message and cause xorg usage 100% of CPU and winecfg responds very slow.

Code: Select all

xrandr --q1

I have tried below command but not work

Code: Select all

winetricks orm=backbuffer glsl=disable

However, if I detach the external screen, xrandr --q1 shows below:

Code: Select all

 SZ:    Pixels          Physical       Refresh

 2   1440 x 900    ( 285mm x 175mm )   53  
 3   1366 x 768    ( 271mm x 150mm )   54  
 4   1280 x 1024   ( 254mm x 200mm )   55  
 5   1280 x 800    ( 254mm x 156mm )   56  
 6   1280 x 720    ( 254mm x 140mm )   57  
 7   1024 x 768    ( 203mm x 150mm )   58  
 8    800 x 600    ( 158mm x 117mm )   59  
 9    640 x 480    ( 127mm x  93mm )   60

And then xorg back to normally low CPU loading and winecfg responds fast. I have tried other windows program (LINE), same result
So, how to have window programs respond normal when having two screens?
