Brightness is low with hardware acceleration

[ilovespicynoodles]

This is not limited to the app, but i don't know where else to find people working on Linux Geforce NOW issues. So the issue is that when hardware acceleration is on (which is necessary to play without incredible input lag), the brightness in Geforce NOW is way to low and its hard to play certain games. This issue does not happen on windows.

As you can see, the top one, where hardware acceleration is enabled with the LIBVA_DRIVER_NAME=iHD environment variable, is dark and can be incredibly hard to play with.

The bottom picture is without hardware acceleration and has normal brightness, but is unplayable because of input lag.

I remember having this issue in the beginning too and i fixed it, but i don't remember how i did it. I'm using Nvidia optimus which is a nvidia gpu with a intel integrated graphics that i can switch between.

The same issue happens in a chromium browser if i use the flags in the commandline to launch it with hardware acceleration. for example:

chromium --enable-gpu-rasterization --enable-oop-rasterization --enable-zero-copy --ignore-gpu-blocklist --use-gl=desktop --enable-accelerated-video-decode

If i take away --use-gl=desktop, then it runs without hardware acceleration and everything is bright but with massive input lag.

I remember it working on KDE and XFCE4 before but i don't remember how? I was able to just install the intel-media-driver and start up the geforcenow-electron app and it would work perfectly with normal brightness. but now its all dark.

Here are my graphics processors and other system info:

I had a similar issue with GFN, I turned off HDR on my monitor and all the brightness was fixed in my GFN games.

I sadly don't have HDR on my laptop screen :(

I have the same problem on fedora 35, HD Graphics 520.
