Xwayland windows invisible since 3.34.1
On Fedora 31
Seems to be a regression, I didn't have this issue before updating.
Under Wayland, native Wayland windows work fine. So any GTK3 apps aren't an issue. However, launching, for example, Thunderbird, under X11, it loads for a moment, after which nothing is visible. However, the application is running. I can even confirm there's an X window there with lg
.
Trying to interact with a window usually results in the window being clicked through. So if I try to click anywhere on the Thunderbird window, it'll just focus on the window behind it.
These see-through windows still have shadows, and take up space in the overview. As demonstrated in these two screenshots
A fullscreen application, such as a game or video, works completely normally and as expected.
