Linux Mint 20: freeze while using youtube [closed]
Solution 1:
As this is a quite recent system, you could try using later kernel version (5.8 or 5.11). You can do that in the Mint "Update Manager" > "View" > "Linux Kernels".
Another option would be to try whether this also happens with a different Linux distribution as suggested in the comments. Mint has an "edge" Version which has the 5.8 kernel by default.
