Public bug reported: Yesterday, I updated my Ubuntu 20.04.1 LTS and obtained the new official kernel (with the update) 5.8.0-36.
With this kernel I have got a lot of problems with some games with Steam Proton. For example, with the Kernel 5.4.0-59 all works well, I could play Cyberpunk 2077 and Far Cry 5 without problems. Now, with the kernel 5.8.0-36 I can't play Cyberpunk 2077 and I have got low fps in some areas with Far Cry 5, obtaining for example 7-8 fps in the cinematic scene of faith. Some games doesn't start with the new kernel. Some people need this new kernel due to they have got new hardware pieces which are supported with this new kernel. Regards and thank you.
