Works! so what's changed?

This was addressed in the OpenCore 0.6.2 EFI last month, namely:

Which WiFi/BT card are you using?

Didn't reply to your message. sorry.

Hi @CaseySJ, as you said, 3 days of troubleshooting and I've found what causes 3/4 screen wallpaper bug. It is ...automatic login! As soon as I enable it and restart it appears, if I'm disabling it, everything back to normal. Any idea how to fix it?

I get all crashes back again... weird...

DTPG.aml and SSDT-UIAC-VISION-D-V2.aml don't have _OSI ("Darwin") in them, could that be the reason?

Unfortunately there is no solution for this because the USB Vendor Name is not “Apple”. If you use a Fenvi FV-T919 or FV-HB1200 then it might work (but no guarantees).

Those two SSDTs have no effect in Windows so they should be okay. However, because OpenCore allows us to toggle SSDTs on and off individually, please try disabling all SSDTs, then enable them one by one. If problem persists even with all SSDTs disabled, then the problem lies somewhere else.

By the way, which version of OpenCore are you using?

I'm using 0.6.3; I will try your recommendation and report back.

OK, thanks for quick reply! Then I need to switch back to Logitech MX. Could be worse ;-)

Have you tried changing or setting static wallpapers from here?

Weird, but that option is greyed out on Big Sur
