It can’t be because of an “old kernel”. It’s not like RA hooks deep into the kernel. Even if it did, there would be a reason of this behavior, not just because of “an old kernel”. And I do use the latest LTS kernel, and the Sony driver is up to date (fixes are backported) compared to master.
It never happens in-game, only by navigating around in the menu. It can trigger randomly, but always after “something” you did, like closing the content, navigating to a big playlist, adjusting a value down or up (and quite often it gets stuck pressing either left or right, and sometimes alternating betweeen left/right), and it triggers almost everytime when saving the configuration.
I have tried to manually creating the config too. (The values will correspond to the built-in autoconfig, so the values are right).
So I’m left using my xbox s controllers, which kinda sucks since I hate that controller.
