Description Neil Roberts 2014-06-06 16:51:35 UTC

Calling glClear on a framebuffer bound to a multisample texture doesn't seem to do anything. I think this has something to do with the fast clear implementation because if the clear is scissored or the color is changed to something that doesn't have 0.0 or 1.0 in the components then the fast color is disabled and it works.
