I have two large monitors attached which I run as a large single workspace across both screens. I have been running this for years without problem over several Ubuntu releases. Following the recent upgrade (Apr 20 2022), my desktop wallpaper is no longer displayed properly. Almost all of it is covered in solid black except for a very small sliver of the wallpaper at the bottom of each screen. If I change the desktop background there is no effect (except for the small sliver at the bottom of the screen) changes. If I reboot, or if I log in as a different user, there is no change. If I click "Activities" or press the Windows button, the menu of desktops I can switch to is displayed with the correct wallpaper, but when I switch to it it comes out all black on both screens (apart from the icons, any windows and the sliver at the bottom of the screen). I have 2 different laptops which I have upgraded also but those are OK. I've not tried any dual-screen on them. Possibly relevant is that I have an nVidia display controller. It does appear to be a problem that has crept in with the most recent update. Everything else I do is unaffected as far as I can see but I'd just like something different from the boring solid black.
