xwayland: crash originating in glamor_create_fbo

Originally reported here: https://gitlab.archlinux.org/archlinux/packaging/packages/xorg-xwayland/-/issues/2

After updating xorg-server-common from 21.1.11-2 to 21.1.12-1 and xorg-xwayland from 23.2.4-2 to 23.2.5-1, I get random Xwayland crashes when operating IntelliJ IDEA on my work laptop.

They usually happen when quickly switching to some file using the Double-Shift-Action-Dialog, e.g., pressing Shift twice brings up a dialog where you can select files, classes, or trigger actions and narrow everything by typing in phrases. When the class or file I was looking for has been selected in that dialog, I hit return which should close the dialog and open the found file in a tab in the IntelliJ main window. That's the point where the crashes appear, i.e., I hit return and out of sudden, the IntelliJ window disappears.

Here's a backtrace retrieved from a dump using gdb: Xwayland_backtrace.txt I can also upload the core dump somewhere if requested.

The crash might be related to #1656 (closed).
