Created attachment 468858 [details] Patch to enable ForceCompositingMode for WinCairo Enabling ForceCompositingMode for WinCairo resovles the assertion failure. This seems to be the reason why Mac WK2 and WPE don't crash.

Comment 3 2023-12-03 22:10:35 PST
Mac WK1 doensn't crash because it skips the assertions. See bug#188122. GTK and WinCairo should do the same.
