So - heres a weird one.

Everything was completely fine until last night and I have no idea what has changed at all.

When my screen sits idle for more than a second it get fuzzy and blurry. Then it will pulse from fuzzy to clear about every second.

Every letter I type causes the screen to flash clear, but then immediately goes back to fuzzy after I release the key. Mousing over an entity that causes an interaction does the same thing.

It is not the HDMI cable. Ive tried 3 cables. Its not my HDMI switch, I’ve changed all the cable and swapped ports around several times.

I have a SAMSUNG 43 UHD TV (60hz) that I use as my monitor. It is set to Dynamic Display in Game Mode. This has worked with no issues at all for 6+ months.

I ran some system updates 2 days ago, but the issue didn’t start until last night. Also - its intermittent - so I’m at a total fucking loss. Reboots/Resets of varying types have not seemed to help.

Any ideas? let me know what else you need from me - Im still a relatively new linux user so be gentle.

Thank you in advance

    I wonder if your Samsung TV got an update that is causing a conflict. Is it connected to the internet?

      I think I actually fixed it?

      i tried to do an os refresh but kept getting some generic error bc the backup partition wouldnt update?

      after a bunch of fumbling around I actually slowed down and took a second to read the errors and saw an error for a game i had removed.

      so after ducking around (intentional duckduckgo pun) i found the sudo apt purge command and zapped it

      then i followed https://support.system76.com/articles/upgrade-pop/ and some things happened and downloaded and i rebooted

      and its working now? I will know for sure if its working if doesn’t start happening again in an hour.

      but i think it might be good to go based on that experience.

      Edit: continues to work. Might be solid. Will report back tomorrow.

        Follow up - issue came back. I’m thinking it may be hardware or driver at this point. I am going to mess with that this evening and I will report back.

        If that doesn’t work - I will do the os refresh bc I haven’t actually done that yet.

        Edit: this is more of a log for myself at this point, but I am refreshing the os now.

        edit two, the editing: refresh complete. will update tomrrow.

          Okay it’s actually fixed now. Games are running smoothly and shaders are loading better. It must have been a funky driver.

        Unrelated but reading through what might be the issue I’m stealing ducking around, idk how I never thought of that!

          Hahaha - update on issue, it was my switch, but not the switch, I think WHEN I used the the switch (like toggling between my other machine) it made things mad until I rebooted. Then when I rebooted it was fine until I used the switch again. So I just changed the things I used on the switch and everything is kosher now.
