Draft: the Xwayland implicit-sync change reduces but does not remove the GL tear (6 flagged tears / 25 s against 23 on the shipped build in the end-to-end test of this payload). The remaining cause is measured: the guest's MIT-SHM attach is refused by the container sysvshm library, so each frame reaches Xwayland as 15 PutImage bands and commits land between them. A sysvshm fix follows; the DXVK-path changes (daemon flip at latch + A56) are unaffected. |

Superseded by the payload 20261101.2 PR (same branch contents plus the Xwayland from GameNative/xserver#2, which fixes the GL tear this payload still had). Closing. |
