Thomas Lübking a3d502338d delay adding Unmanaged clients by 50ms
This provides some sort of synthetic XSYNC support
for unmanaged clients and allows them to do an initial
update after mapping and before being painted (prevent
flicker)
Also it helps with Unmanaged clients performing quick
map/unmap/map cycles what also seems to induce the black
window issue on the nvidia blob.
