Reported 2020-12-22 10:47:44 PST
Several tests under deqp/functional/gles3/texturespecification/ are failing on macOS with AMD GPUs because of OpenGL driver bugs in the handling of the packed RGB565 and RGBA4444 texture formats. The following tests are failing sub-tests: deqp/functional/gles3/texturespecification/ teximage2d_pbo_2d_00.html teximage2d_pbo_2d_01.html texsubimage2d_pbo_2d_00.html texsubimage2d_pbo_2d_01.html texsubimage2d_pbo_cube_01.html These failures can be worked around by promoting these formats to RGB[A]8.
