1Mesa 20.0.3 Release Notes / 2020-04-01 2====================================== 3 4Mesa 20.0.3 is a bug fix release which fixes bugs found since the 20.0.2 5release. 6 7Mesa 20.0.3 implements the OpenGL 4.6 API, but the version reported by 8glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / 9glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being 10used. Some drivers don't support all the features required in OpenGL 114.6. OpenGL 4.6 is **only** available if requested at context creation. 12Compatibility contexts may report a lower version depending on each 13driver. 14 15Mesa 20.0.3 implements the Vulkan 1.2 API, but the version reported by 16the apiVersion property of the VkPhysicalDeviceProperties struct depends 17on the particular driver being used. 18 19SHA256 checksum 20--------------- 21 22:: 23 24 d63aaf2c27143eded2f4f376f18f7a766ad997f8eeb96c357e8ade84e8a237af mesa-20.0.3.tar.xz 25 26New features 27------------ 28 29Bug fixes 30--------- 31 32- RADV: flickering textures in Q.U.B.E. 2 through Proton 33- src/compiler/glsl/ast_to_hir.cpp:2134: ir_rvalue\* 34 ast_expression::do_hir(exec_list*, \_mesa_glsl_parse_state*, bool): 35 Assertion \`result != NULL \|\| !needs_rvalue' failed. 36- [ACO] Reliable crash with RPCS3 that is not present with LLVM 37- [RADV] vkCmdBindTransformFeedbackBuffersEXT pSizes optional parameter 38 not handled 39- soft-fp64: \__fsat64 incorrectly returns NaN for a NaN input.
