Mesa 21.0-RC5 Released For Testing This Q1'2021 OpenGL/Vulkan Driver Collection

The Mesa release train once again fell off the tracks for Mesa 21.0 but on Friday the fifth release candidate managed to ship.

Mesa 21.0 is running behind schedule for release and there ended up being two weeks since the prior RC4, but in any case Mesa 21.0-RC5 is now available for testing. Given the extra time between release candidates, Mesa 21.0-RC5 does come on the heavier side. There are also still open blocker bugs left so it's possible a Mesa 21.0-RC6 will be warranted in the next week or so before announcing Mesa 21.0.

Among the many fixes for Mesa 21.0-RC5 are improved spilling on discrete GPUs with RADV, ACO RDNA2 fixes, several Zink fixes, Nouveau fixing linear buffer alignment for scanout/cursors, and the usual assortment of fixes to the open-source Intel graphics driver.

The full list of changes for Mesa 21.0-RC5 can be found via the mailing list announcement.

See our Mesa 21.0 feature overview to learn more about the changes with this quarterly update to these open-source OpenGL/Vulkan (and OpenCL and video acceleration) drivers.
