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