[Mesa-dev] Why do vulkan display surfaces not support alpha blending?

2020-03-19 Thread Austin Shafer
Hi all, I noticed on an intel laptop that the only supported alpha mode for any display plane is opaque. Is there a specific reason for this? I'm trying to draw interfaces and things direct to the display and it would be really nice to have alpha blending. >From src/vulkan/wsi/wsi_common_display.
