Hi, I've just noticed a large drop in FPS (from 60 down to 15) when playing World of Warcraft with the latest Mesa from Git. A quick git bisect has identified this commit:
4292fb2139282e6906d4ad2a8be2fd81ed7ca8af is the first bad commit commit 4292fb2139282e6906d4ad2a8be2fd81ed7ca8af Author: Michel Dänzer <mdaen...@redhat.com> Date: Mon Dec 21 15:41:56 2020 +0100 wsi/x11: Use PresentOptionAsync for MAILBOX present mode with Xwayland This allows Xwayland to forward buffers to the Wayland compositor ASAP for fullscreen / undecorated windows, which in turn allows true mailbox behaviour in the Wayland compositor. Without this, Xwayland has to emulate the mailbox behaviour itself, which it cannot do as well as the Wayland compositor by design.
