[gtk4] Partial window rendering; GL command queue too large
Repeat #2757 (closed)'s test case with the gtk4 test app. Preferably the echo
variant because then the command line also contains such characters, not just the output (more of the canvas is box drawing).
Do this in a large (maybe maximized/fullscreened) terminal, smaller font size if necessary.
As I reach the bottom of the window and the contents start to scroll, I get rendering failures. About the top 3/4 of the window is rendered correctly, the bottom 1/4 remains blank or mostly blank.
After a mouse selection / unselection the headerbar of vteapp isn't painted properly either.
On stderr this appears:
(Terminal:11487): Gsk-CRITICAL **: 12:34:57.442: GL command queue too large, truncating further batches.
GTK 4.12.3, vte 0-76
