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&test=fast%2Fcanvas%2Fwebgl%2FtexImage2D-mse-flipY-false.html&platform=mac&flavor=wk2&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.

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.

This text expectation was removed by mistake in 267723@main (the issue has not yet been resolved -- see rdar://problem/114642707). Re-setting test expectation.
