    <thetext>fast/canvas/webgl/texImage2D-mse-flipY-false.html

This test is a consistent text failure on macOS wk2 (including gpuprocess).

HISTORY:

https://results.webkit.org/?suite=layout-tests&amp;test=fast%2Fcanvas%2Fwebgl%2FtexImage2D-mse-flipY-false.html&amp;platform=mac&amp;flavor=wk2&amp;flavor=gpuprocess

TEXT DIFF:

 Setting video src.
 Video can play.
 Checking the canvas pixels.
-PASS: Bottom edge is red.
-PASS: Top edge is blue.
+FAIL: Bottom edge is not red.
+FAIL: Top edge is not blue.

DIFF URL:

https://build.webkit.org/results/Apple-Ventura-Release-AppleSilicon-WK2-Tests/267407%40main%20(4683)/fast/canvas/webgl/texImage2D-mse-flipY-false-pretty-diff.html

REPRODUCTION:

I was able to reproduce this bug on macOS Ventura (13.5, 22G74/arm64) using the following command:

run-webkit-tests --verbose --iterations 50 --clobber-old-results --exit-after-n-failures 1 fast/canvas/webgl/texImage2D-mse-flipY-false.html

REGRESSION:

I was able to bisect a regression point. This bug reproduced at 267279@main, but it did not reproduce at 267278@main. Changes at 267279@main appear to be directly related to this error, and is likely what caused the failure.</thetext>
