Mesa 21.3.5 Release Notes / 2022-01-26 — The Mesa 3D Graphics Library latest documentation

# Mesa 21.3.5 Release Notes / 2022-01-26

Mesa 21.3.5 is a bug fix release which fixes bugs found since the 21.3.4 release.

Mesa 21.3.5 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 21.3.5 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.

## New features

- None

## Bug fixes

- glGetActiveUniform failing with GL_INVALID_VALUE for no reason

- CopelliaSim crashes on adding vision sensor to a scene on Ubuntu 20+, runs fine on Ubuntu 18.04

- Dirt Rally: Flickering glitches on certain foliage going from Mesa 21.2.5 to 21.3.0

- FrontFacing input is broken on Intel/Vulkan

- llvmpipe: Unimplemented get_driver_uuid/get_device_uuid causes segfaults in e.g. Wine
