Hello @guustflater, this looks like other 30 bit color regressions seen with that feature enablement in mesa.
See if adding <option name="allow_rgb10_configs" value="false" /> to the device section in /etc/drirc and relogging / restarting X makes a difference.
Wow, this is amazing!!! It works perfectly!!!!!! Thank you so much!!!!
If you don't want to disable rgb10 globally, you can wrap the option in an application tag:
<application name="Steam" executable="steam">
<option name="allow_rgb10_configs" value="false" />
</application>
I seem to have the same or a similar problem streaming from a Windows host to a Kubuntu client.
The colors look almost inverted and very dark, it's hard to even recognize what is on the screen.
So far whether disabliing rgb10 nor switching the output device from IGP to dedicated grapics card did help.
Here's Flatout 2 for example:

It should be noted that this has been working before. The only somewhat major change to the system that comes to my mind is a BIOS update (client device is a Thinkpad S531 20B00050GE).
Please let me know if I can provide more information to help identify/resolve this issue.
I'm getting exactly the same corruption as the poster before me. I'm running Crouton on an Acer Chromebook 14, and it's worked perfectly before, but now I'm getting the same issue. Sorry if my description isn't very useful, I'm happy to add more information if needed.
Hello @mdPlusPlus, @TSDAdam, unless the driconf workaround above has an effect, you're seeing #6066, not the issue tracked here.
The beta fixed this for me. Hope the release can be expected soon: Imgur
Experienced this from Linux to Linux and Windows to Linux.
Hi @kisak-valve steam won´t run for me when using 10 bit per color on the nvidia proprietary drivers should I open a bug report?
