For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", then attach the output file (dxdiag.txt) on your next reply.
Could you also send us a screenshot that shows the wrong colors?
PS: Attach option should be visible on your side after your second post.
Thanks for sending the requested files.
Could you please try to update your AMD driver to the most recent version.
You can download the driver installer from their website: https://www.amd.com/en/support/graphics/amd-radeon-5700-series/amd-radeon-rx-5700-series/amd-radeon-rx-5700-xt
After the driver update, please reboot your primary machine and try again with spacedesk.
Then let us know if the problem still persist.
@jameszhu3rd, I've had this issue and believe I know how to resolve it for you, if Lea's suggestion has not worked.
I also have an AMD GPU and experienced the same issue previously. I have a HDR monitor, and had the option under Graphics -> Advanced for "10-bit Pixel Format' enabled.
Disable this option, and your colors should return to normal when you use SpaceDesk.
@spacedesklea - I've seen this issue going on at least the last five months through different AMD driver versions and multiple Spacedesk server & viewer versions. Spacedesk seems to be the only app that doesn't work correctly with 10-bit Pixel format enabled, however.
