I hate myself to saying this… buy nvidia is also a option 
And i had a big issues with my nvidia card (last year) and flickering display for around 6month till the error was fixed by nvidia and required a workaround fix where my nvidia 2080Ti used 50 Watt in idle instead 10Watt for several month.
But since this licensing issue is there, im not sure if i would bought a AMD GPU Card in future.
Is there any light at the end of the tunnel? And how this problem are handled within the other distro’s?
Few month ago, there was a bug for the ext4 filesystem, affected was even the people like me with backported in LTS Kernel in stable branch… this bug introduced data corruption in the filesystem. 
Lucky i just had this cursed Kernel update for only 10 days on my system and didnt refreshed my backup in this time 
Edit:
I found the Info from this
