[Bug 1925320] Re: Backport packages for 20.04.3 HWE stack

[Mateusz Stachowski]

In my case the new mesa causes graphical glitches.

It happens in Unity and Gnome Shell both X.org and Wayland sessions.

CPU:
  Info: 6-Core AMD Ryzen 5 3600 [MT MCP] speed: 3916 MHz 
  min/max: 2200/3600 MHz 
Graphics:
  Device-1: AMD Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] 
  driver: amdgpu v: kernel 
  Display: x11 server: X.Org 1.20.11 driver: loaded: amdgpu,ati 
  unloaded: fbdev,modesetting,radeon,vesa resolution: 1920x1080~60Hz 
  OpenGL: renderer: AMD Radeon RX 5600 XT (NAVI10 DRM 3.35.0 
  5.4.0-79-generic LLVM 12.0.0) 
  v: 4.6 Mesa 21.0.3

I also have kernels from XanMod 5.12.13 and 5.13 and when using those
there is the same problem.

Bug description:
  [Impact]

  These are needed for 20.04.3 images.

  [Test case]

  Boot a daily image, see that it still has the necessary stack
  installed and working.

  [What could go wrong]

  directx-headers: a new package, nothing can go wrong

  libdrm: adds some new api, no changes to old stuff

  llvm-12: a new package, no regression potential on it's own

  mesa: a new major release, but we'll pull the final stable release of
  21.0.x series, so there shouldn't be any regressions left at that
  point

  xserver: a new point-release, 1.20.x series is in deep maintenance
  mode, so there should be little chance of breakage
