loader/dri3: Also wait for front buffer fence if we triggered it
In that case, we have to wait for the fence to synchronize with the corresponding drawing we triggered in the X server. Fixes incorrect display with the i965 driver and some applications, e.g. solvespace. Bugzilla: https://bugs.freedesktop.org/108097 Fixes: aefac10fecc9 "loader/dri3: Only wait for back buffer fences in dri3_get_buffer" Tested-by: Sergii Romantsov <[email protected]>
