HDR worked in KDE Plasma on a 4090. Stopped working after upgrading to a 5090.
Hello. I recently built a new PC and installed Bazzite on it. Before I put a 5090 in it, I had the RTX 4090 from my old PC. HDR was working native within KDE, and also worked in Gamescope.
I installed the 5090 and booted up Bazzite, expecting things to just work. However, while my displays worked, HDR enabled on KDE resulted in a washed out display. I'm not sure what the problem is, but I suspect it's a driver issue.
I tried enabling and disabling HDR with no change, and updated Bazzite to the latest image. HDR continues to show a washed out image.
Any idea what's up? I could go down the Arch linux route so I can get on the latest kernel and maybe beta nvidia drivers, but I really like how clean Bazzite is right out of the box.
Thanks for any info you can provide.

nvidia needs to fix it, we have 0 control over the nvidia driver
I figured it was an nvidia problem. Just wanted to see if anyone had further insight into the issue. Thanks.
So I'm 99% sure HDR will be fixed for me if we can get the latest nvidia driver on bazzite. It just was released https://www.nvidia.com/en-us/drivers/unix/ Latest Production Branch Version: 570.133.07
"Fixed a bug that could prevent RTX 50 series GPUs from enabling HDR on certain HDMI displays, resulting in washed out HDR content."
Not sure how long it takes the Bazzite maintainers to update a driver like this, but I hope it's soon!
