Quoting: Vinouchwith RX 5600 XT latest proprietary driver

Just curious. Why don't you use Mesa? Does it also have the same problem?

ACO only works with the Mesa radv driver. Maybe you checked the ACO checkbox in Lutris but didn't notice it has no effect?

In most games (90% or even more) the Mesa drivers is faster than the proprietary driver, not to mention that Valve does theirs in house testing with the Mesa driver. No reason to use the proprietary driver only a few games run faster with it. Feral and others developers, officially support the Mesa driver, have not seen any game developer explicity supporting the proprietary driver ever.

When I installed the GPU, I had the following bug from Ubuntu, so I installed the AMD propr driver (same issue as well). So now, I will follow your advices and reinstall the default driver and I will come back to tell what about it. https://ubuntu-mate.community/t/20-04-display-issues-with-amd-gpu/21648

If you're still having problems, install a newer kernel. Mainline (free fork of UKUU) makes that really easy. You can find it in this PPA. I suggest grabbing the latest stable kernel on offer. Don't worry, you can easily boot back to the system provided one.

You'll probably want the latest stable Mesa as well, seeing as your GPU is quite recent. My favourite source is Kisak's excellent PPA.

I prefer keep a stable profile and not switch kernel, neither try a driver from ppa. I'm not that kind. About my game assassin's creed origins with ACO enabled, now with mesa driver, same issue. But currently, enabled or disabled in this game don't change fps performance, so I play with it disabled.

If you are using AMD use the latest kernel. Nothing wrong with that. Otherwise, you'll have issues, so that's expected.

An alternative approach is to use older kernel with latest amdgpu through dkms. But I don't see a need, unless you know exactly why older kernel is better for something else.

Using the proprietary driver goes against this principle, in a sense.
As it was mentioned, newer hardware needs newer system components. It's as simple as that.

Using the 5.8 is a must I would say Mesa I think you are okay, but you need to use 5.8, since a lots of bugs were fixed, if you don't want to use 5.8 you'll have troubles. I had freezes with kernels older than 5.6.

You are very affirmatives without proof. Please support your claims with reliable sources.
