Rainbow flickering bug

https://youtu.be/Em5UfM5oM30?si=nGY7tPOVaujVx3gF

I'm experiencing a visual bug where a rainbow effect flickers on the right side of my screen. It varies in size and can get as big as the whole right side of my screen . It comes and goes, I've noticed it popping in when Alt-tabbing, but I can't say for sure if that's what's causing it. I've experienced this bug on both, POE and now POE2. When I first noticed it on POE1 I thought maybe it was my graphics card, but it's something I've only ever encountered when playing POE1, or POE2. I also noticed that when I alt-tab, I can see multiple windows of POE2 opened (1:11 of video for example), but on my task bar and task manager there's only one? POE2 is such an aesthetically beautiful game, and I've been trying to take my time to really enjoy how beautiful the game is, but this bug is making it hard to.

I have the same issue. It only occured when I switched back from alt-tabbing (and only in this game)

Same problem here. I have it since today. Didn't have it yesterday. Might be because I tabbed a lot but Idk rly. It flickers in different colors on the right side of the screen and changes size when I walk sometimes. Annoying.

Posting in case anyone finds a fix. Same issue after alt tabbing too many times.

Yes, it happens to me too, I can play for a long time, but the moment I alt+tab, I start to see that glitch, I'm sure it's because I'm using DX12 with FSR in quality mode.
The solution I found is:
1) alt+tab again and the rainbow disappears
2) change dx12 to vulkan
3) use dx12 with NIS (not FSR)
4) use dx12 with FSR in balance

The best option for me is 2), because im also experiencing a weird bug in dx12 where the GPU goes nuts to 100% and my fps drops from 72 fps (capped and constant) to 37 fps and the solution is alt+tab, again.

Same issue, mostly in hideout, but rarely in other areas too. I changed from DX12 to Vulkan which did incidentally improve performance especially right after loading but sadly that issue still exists.

Win 10, Ryzen 2600X, RX6600, 32GB 3200MHz, Driver 24.12.1, the game is on a Samsung 970 EVO M.2 1TB drive with plenty of space left. High settings with FSR.

Same issue without alt tab, mostly in hideout.

Gpu or game?

any fixes for this ?

experiencing the same issue. not fixed so far unfortunately

Similar, but mine is a blue-white glow and seems related to certain effects/mobs (I'm using lightning skills and it has that theme's color scheme) ... it looks like the screen when old tube tvs get magnitized, and is imo related to existing effects and mobs. It is only about 5-10% of the screen though, and is more concentrated to the center of the far right of the screen in a glow/fading bubble way. It also comes and goes.

Def seems related to tabbing in and out of the program, doesn't start until I do.
