I am running tests in ci on the new windows 11 update, and there are some failures.

some errors from a debug log:

you can see this happens frequently enough and my script to "green up" added an annotation for this test. I have a patch to disable this on the new windows version here, and we plan to deploy that in 2-4 weeks, when most changes have been checked in.

this bug is fined as a work item for the panning and zooming team to investigate this when time permits.

If you want to investigate this and run on try server, here is a command to use:
./mach try fuzzy -q 'test-windows11-64 browser-chrome' --worker-override='win11-64-2009=gecko-t/win11-64-24h2' --worker-override='win11-64-2009-gpu=gecko-t/win11-64-24h2-gpu' --worker-override='win11-64-2009-source=gecko-t/win11-64-24h2-source' --worker-override='win11-64-2009-ssd=gecko-t/win11-64-24h2-ssd' --worker-override='win11-64-2009-ssd-gpu=gecko-t/win11-64-24h2-ssd-gpu' --push-to-vcs gfx/layers/apz/test/mochitest

This test is going to be removed soon as its contents are being ported to mochitest-plain in bug 1841896.
