The explicit sync stuff can still fix a few games, best to try it for yourself. Of course, the driver side changes will be required to completely fix the issue, but for me with just the XWayland patches, doom eternal, Elden ring and Skyrim are playable again for me!!
No need to compile yourself, Lawnchair is NOT dead.
Join their telegram group, they share Dev builds there. Or, you can install Gooolers builds from GitHub: https://github.com/Goooler/LawnchairRelease
Personally I use Gooolers.
