Some drivers don't support all the features required in OpenGL 4.5. OpenGL 4.5 is <strong>only</strong> available if requested at context creation. Compatibility contexts may report a lower version depending on each driver. </p> <h2>SHA256 checksums</h2> <pre> 2a369b7b48545c6486e7e44913ad022daca097c8bd937bf30dcf3f17a94d3496 mesa-19.1.6.tar.xz </pre> <h2>New features</h2> <p>None</p> <h2>Bug fixes</h2> <ul> <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=104395">Bug 104395</a> - [CTS] GTF-GL46.gtf32.GL3Tests.packed_pixels.packed_pixels tests fail on 32bit Mesa</li> <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=111213">Bug 111213</a> - VA-API nouveau SIGSEGV and asserts</li> <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=111241">Bug 111241</a> - Shadertoy shader causing hang</li> <li><a href="https://bugs.freedesktop.org/show_bug.cgi?id=111411">Bug 111411</a> - SPIR-V shader leads to GPU hang, sometimes making machine unstable</li> </ul> <h2>Changes</h2> <p>Andres Rodriguez (1):</p> <ul> <li>radv: additional query fixes</li> </ul> <p>Daniel Schürmann (1):</p> <ul> <li>nir/lcssa: handle deref instructions properly</li> </ul> <p>Danylo Piliaiev (1):</p> <ul> <li>nir/loop_unroll: Prepare loop for unrolling in wrapper_unroll</li> </ul> <p>Ian Romanick (2):</p> <ul> <li>nir/algrbraic: Don't optimize open-coded bitfield reverse when lowering is enabled</li> <li>intel/compiler: Request bitfield_reverse lowering on pre-Gen7 hardware</li> </ul> <p>Ilia Mirkin (1):</p> <ul> <li>gallium/vl: use compute preference for all multimedia, not just blit</li> </ul> <p>Jonas Ådahl (1):</p> <ul> <li>wayland/egl: Ensure correct buffer size when allocating</li> </ul> <p>Juan A.
