+Subject: [PATCH] meson: Add xcb-fixes to loader when using x11 and dri3. Fixes
+ undefined symbol for xcb_xfixes_create_region in loader_dri3_helper.c
+
+loader_dr3_helper.c uses xcb_xfixes_create_region() that requires dep_xcb_xfixes to link. This is dependent on with_platform_x11 and with_dri3.
+But the source meson file does not set this up dependent on with_dri3.
+The build was initialsed using platforms=x11 and gallium-drivers=zink,swrast.
