I saw what looks like the same issue under Wayland today. It was slightly different than what I had seen before in that I had one window (Chrome) that wasn't black. All others were. The issue started when I clicked to upload a file to a web page. The Chrome window went subdued, which it normally will do when it's launching the file chooser to select a file to upload, but the file chooser came up all black, and Chrome remained subdued and unresponsive (at least in that tab). Other application windows were also all black, including newly launched ones (tried another Files and also a Terminal window).
Logging out and logging back in corrected the behavior. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1799947 Title: [radeon] Application windows in 18.04.01 go black but launcher is still visible Status in gnome-shell package in Ubuntu: Incomplete Status in mesa package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: Intermittently and randomly, all application windows will go black. They are still there, and can be interacted with with keyboard shortcuts or if you know where to click with the mouse, but they are not drawn. The launcher itself is still displayed. Clicking Show Applications briefly draws the application window before switching to the background and application icons. The application icons are shown correctly. Selecting one switches to a black window for that application. The application window is again briefly displayed when dismissing the application icons by again clicking Show Applications. TTYs work normally. Killing gnome (from another TTY) and allowing it to relaunch results in a normal display again. This is being seen on an hp 6910p. This system also exhibits a corrupted lock screen since upgrade to 18.04.01. Neither of these behaviors were seen during two years running 16.04.01. Chrome is being used. Current 70.00.3538.77 (64-bit). Chrome is the most commonly used application on this machine, so it is possible that the behavior is being triggered by Chrome, however, the behavior affects all applications, including system applications like software update and terminal.
