I'm using an AMD RX 6800 XT

I have the same issue with an Intel UHD Graphics 630 (CPU:Intel i7-10700) in my office computer but also with my MSI RTX 2070 Super (CPU: Ryzen 2700x) in my home computer.

Edit: My Laptop HP Envy x360 15-eu0xxx with a "AMD Ryzen 5 5500U with Radeon Graphics"-CPU has the same issue.

@erkenes, just would like to double check, on those Intel and NVIDIA GPU, do you see same issue as @mrtolkien, which is half diagonal is rendered correctly but other is blank? Or entirely blank like below screenshot? thanks!

Exact Same issue here on a 6900xt, 21.5.2 driver version Microsoft Windows [Version 10.0.22000.1098]

It is a diagnol cut on my end. I have multiple monitors attatched. Only one of my attatched monitors has Windows scaling enabled, but it's not my primary monitor.

I have the same issue like the OP. The half diagonal is rendered correctly but the other is blank.

Edit: My Laptop HP Envy x360 15-eu0xxx with a "AMD Ryzen 5 5500U with Radeon Graphics"-CPU has the same issue.

@erkenes, @MasterJubei, would you please disable Display Driver from Windows's device manager, and restart WSL by wsl --shutdown, and reinstall Ubuntu 22.04? Once Ubuntu installation is completed, reenable Display Driver, I think this is the best workaround for this issue for now, thanks!
