There are some existing tests that seem to be flaky:
``` on test-win10-21h2-32: render.c:1409: Test failed: GetBuffer large (22500) at iteration 4 render.c:1409: Test failed: GetBuffer large (22500) at iteration 6 render.c:1409: Test failed: GetBuffer large (22500) at iteration 7 2744:render: 2330 tests executed (0 marked as todo, 3 as flaky, 3 failures), 2 skipped. ```
I've also stumbled upon those while testbotting my changes.
