Intel UHD Graphics 620 only works as intended if dri3 is enabled

[ShulaSharuba]

This is my 20-intel-conf file after running the setup script:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "SwapBuffersWait" "true"
   Option      "TearFree" "true"
EndSection

This is the result:

Here is the dri3 fix:

Section "Module"
   Load "dri3"
EndSection

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "SwapBuffersWait" "true"
   Option      "TearFree" "true"
   Option      "DRI" "3"
EndSection
