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
