Green Corruption/Artifacts after Update

Ask Fedora
1

I’m not sure if this is the correct place to put this since I don’t really need help with the issue but I’d still like to report the experience I had. I was using Fedora KDE Plasma. After an update on the 30th, I believe it was labeled a “Package Update” around 500-700mb, I restarted and as soon as I got to the log-in screen I noticed some flickering/flashing from my primary monitor. This flickering/flashing was a large horizontal mainly green line across the screen kind of like what you’d see on a CRT. It was only showing up on my primary monitor (AOC AG493UG7R4).

I was already getting ready to reinstall my old distro since I was having some other issues. I noticed as I reinstalled from the live cd, this green artifact issue was still happening. It even got worse and filled the entire screen. It looked kind of like VRAM artifacts but I didn’t notice any of the random symbols you’d usually see with that. I decided to turn that monitor off, waited a minute, and turned it back on and I haven’t seen those artifacts since. I wish I could be more help in finding the cause, but I was already mid way through the install before I realized.

I didn’t have freesync enabled in my monitor’s OSD, I was having some problems getting the flickering to go away in KDE Plasma so I resorted to completely disabling it.

I don’t have Fedora KDE Plasma installed anymore but here’s my system info:

I notice that you seem to be running Linux Mint with kernel 6.8.0

This forum is clearly, by its name, dedicated to support of Fedora and does not diverge into supporting other distros.

You have posted on the wrong forum and should probably take the issue to a forum that supports ubuntu distros.

This does sound quite a lot like a transient hardware issue, not software.

If the updates to your previous Fedora installation had been problematic, you wouldn’t have seen the same issues with the LiveCD (where the software is ~5 months old).

I was running Fedora KDE Plasma when the issue happened.

I’m not saying it isn’t but I haven’t seen any issues like that before that specific update. I also don’t have those issues right now. So I don’t think it’s a hardware issue but who knows.

Edit: In my ignorant user opinion, I think it has something to do with DDC/CI. In a similar way to how you can turn off your power supply to fix issues sometimes, I think I cleared the corrupted data by turning it off for a bit.
