18:52 uis: Goal: do multisampling with color correction. Question: how can regular OpenGL do resolve without hitting main memory? EXT_multisampled_render_to_texture seems to be GLES-specific.
18:57 uis: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24262#note_2779964 suggests I have to do render-blit-invalidate dance and pray for driver to notice pattern and resolve without store-loading
19:02 uis: Is MSAA resolve done in shader core or as fixed function? Is it on other GPUs? If so, can drivers detect pattern of render-recolor-invalidate?
19:03 uis: *so = in shader
