freedreno: Fix KHR-GLES31.core.texture_cube_map_array.color_depth_attachments
This test has annoyingly little logging, but what I've managed to figure out so far:
- Failing color attachments for both layered and non-layered; depth attachment is fine
- Failing only for certain dimensions, possibly a layout issue?
- fail: 8x8x8, 256x256x1, 173x173x3 (w x h x nlayers)
- pass: 64x64x3, 117x117x1
- with notile, 117x117x1 also fails; noubwc has no effect
- The bad color pixels seem not to be drawn, ie. expected result is
{ n_layer, 0, 0, 1 }
, if I change the frag shader to add one to output, the bad pixels are still{ 0, 0, 0, 1 }
