Comment on attachment 191779 [details] Patch Is there some scenario where the problem is shown? Ideal would be if there was a test showing the problem.
It showed up in the DRT test fast/canvas/webgl/gl-object-get-calls.html
(In reply to comment #5) > It showed up in the DRT test fast/canvas/webgl/gl-object-get-calls.html What effect does your change have on this test? Is it an improvement? If the test result is different you may need to add the new test result to your patch.
There is no change to the actual test.
(In reply to comment #7) > There is no change to the actual test. Ok, then we need to go back to your earlier remark: > It showed up in the DRT test fast/canvas/webgl/gl-object-get-calls.html How did it show up, as a warning?
