Compute Shader output shows all black pixels
Dear developers,
I was trying out running compute shader test cases on a QEMU based virtual machine. Underlying OS is Red hat enterprise linux. Problem is all compute shader pixel are black around the triangle. But, golden output has colorful rectangles around grey triangle. I can't figure out, what can go wrong.
virglrenderer is already installed in the host (ubuntu-20)
