backend/x11: Revert usage of present extension
This reverts commit3317134adf. This reverts commita3c3b928a3. There are some serious issues when running this on a real X server, as opposed to running this on Xwayland, where this was tested. More investigation needs to be done into why these issues happen and if our usage of the present extension is correct.
