For some reason this has been going on for about a week. In Endfield the texture is broken (either black or blocky). In Wuthering Waves the colors on the character model are sometimes wrong, and I get multiple flares while moving the camera. I'm using the latest Flatpak version (2.20.1) with Mesa 25.3.5. I've also tried the latest deb version (also 2.20.1) with Mesa 26.0.3 and still have the same issue. This doesn't happen when I launch the same games with Steam. Both games also ran fine on Heroic about a week ago.
