WWE 2K24 released recently and at least for those with an AMD GPU (like the Steam Deck) there were various graphical issues, but it should now work better. Plus, Valve are looking into issues with Red Alert 2 in Proton.
For WWE 2K24, Valve developer Pierre-Loup Griffais posted on X:
A mitigation fix has just been deployed for a graphics corruption issue in WWE2K24 and will be automatically deployed.
I had to do a little searching around to figure out what was actually done, as it turns out they've set the "RADV_DEBUG=nodcc" Mesa environment variable by default which disables Delta Color Compression (DCC) on images. So hopefully that game should play better now.
Recently the Command & Conquer The Ultimate Collection also released on Steam but multiple titles in it have problems running on Linux with Proton. For Red Alert 2 issues in Proton in reply to a user on X Griffais mentioned that the blank screen for a main menu is "currently being investigated".
