Mesa 20.0.3 Release Notes / 2020-04-01

+ +

+ Mesa 20.0.3 is a bug fix release which fixes bugs found since the 20.0.2 release. +

+Mesa 20.0.3 implements the OpenGL 4.6 API, but the version reported by +glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / +glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. +Some drivers don't support all the features required in OpenGL 4.6. OpenGL +4.6 is only available if requested at context creation. +Compatibility contexts may report a lower version depending on each driver. +

+Mesa 20.0.3 implements the Vulkan 1.2 API, but the version reported by +the apiVersion property of the VkPhysicalDeviceProperties struct +depends on the particular driver being used. +

+ +

SHA256 checksum

+TBD.

RADV: flickering textures in Q.U.B.E. 2 through Proton
src/compiler/glsl/ast_to_hir.cpp:2134: ir_rvalue* ast_expression::do_hir(exec_list*, _mesa_glsl_parse_state*, bool): Assertion `result != NULL || !needs_rvalue' failed.
[ACO] Reliable crash with RPCS3 that is not present with LLVM
[RADV] vkCmdBindTransformFeedbackBuffersEXT pSizes optional parameter not handled
soft-fp64: __fsat64 incorrectly returns NaN for a NaN input. It should return zero.
Hang when using glWaitSync with multithreaded shared GL contexts
