Details

Test cases added to the WebGL conformance suite in:
https://github.com/KhronosGroup/WebGL/pull/3045

are failing (some intermittently, some reliably) in Firefox Nightly 76.0a1 (2020-03-23) (64-bit) on macOS. (Have not been able to test on other platforms.)

To resolve this, per the WebGL specification:
https://www.khronos.org/registry/webgl/specs/latest/1.0/#READS_OUTSIDE_FRAMEBUFFER

Firefox's copyTexSubImage2D operation must clip the source rectangle to the bounds of the current framebuffer.

Priority: -- → P1

This runs clean on Windows with and without ANGLE.
