[0.12.9] Screen Flashing On Server

[tyty4646]

I recently joined a server and they updated from 0.12.8 to 0.12.9 a few minutes after the release, and all online members seem to be having the same problem. The factorio screen sort of "flashes" randomly. It also freezes and unfreezes the game every time it happens. This may be a server problem, but just in case I am reporting this bug because everyone on the server experiences this every time they try to get work done. The flashing makes the game nearly impossible to play. The server IP is here: 107.172.11.210:34196

The problem did not occur on any other developmental update.

Moved to duplicates. On my server I reverted to 0.12.8 after two clients reported this issue.
