Describe the issue

All webkitgtk using apps just show a blank webview (either light with a light theme or dark with a dark theme). The cursor does change when hovering over invisible links.

This only happens when logged into a GNOME/Ubuntu on Wayland session. Either running in an Xorg session or with the WEBKIT_DISABLE_COMPOSITING_MODE=1 prefix works around the problem.

Regression

This issue started happening after the upgrade to mesa 22.0 (continued with 22.0.1) and goes away when I revert back to mesa 21.3.5-1ubuntu2
