Square glitch on main screen

[caiocvsilva]

When using VirtScreen whenever I move the cursor from one screen (main) to the other (virtual), a glitch occurs on the main screen, a square showing the cursor and a small part of the background. The same happens if I try to take a screenshot, no matter the screen.

was this after you added in the 20-intel.conf file?

if so i was experiencing same issues where the main screen would be distorted or glitched out, just solved it by deleting 20-intel.conf file.

I am having the same issue here, on this Asus Zenbook.

jcrodriguez@zenbook:~$ l /usr/share/X11/xorg.conf.d/
10-amdgpu.conf  10-radeon.conf        30-virtscreen.conf  70-wacom.conf
10-quirks.conf  11-nvidia-prime.conf  40-libinput.conf

This is the only file I created for virtscreen (it is copied from here):

jcrodriguez@zenbook:~$ cat /usr/share/X11/xorg.conf.d/30-virtscreen.conf 
#Then configure intel internal GPU
Section "Device"
	Identifier "intelgpu0"
	Driver     "intel"
	Option     "VirtualHeads" "1"
	Option     "DRI" "3"   #OPTIONAL: I was having graphics issues without this one
        Option     "TearFree" "true" #OPTIONAL: Force tearing fix
EndSection

I had to delete the Identifier "nvidiagpu0" section, as the computer was not booting. I am not using proprietary drivers.

Thanks! This worked on my Thinkpad T450.
