### No hardware acceleration since Sway 1.10
Typically this results in error messages like these:
```
vulkan: No DRI3 support detected - required for presentation
Note: you can probably enable DRI3 in your Xorg config
```
or
```
DRI3 not available
```
or VA-API fails to initialize.
Sway 1.10 has removed support for the legacy `wl_drm` Wayland protocol, which is still used by Xwayland 23.2.4 and earlier, libva 2.20.0 and earlier, and AMDVLK.
As a workaround, the legacy `wl_drm` Wayland protocol can be re-enabled manually by passing `-Dlegacy-wl-drm` to Sway.
