I've turned down the graphics and similar corruption had occurred, however this time is also crashed the game a few moments later (most likely unrelated to this issue and instead linked to other issues that have been brought up in this forum with different threads: https://forums.factorio.com ...

I am also experiencing this issue on macOS with Intel HD 6100 graphics.

I was playing on the newly released 15.10 update, and after I went to the map view, I noticed the shaders got severely corrupted when returning to the game view.

Upon looking at the server stout, this is what the server was logging:


May 06 02:48:37 ip-xxx-xxx-xxx-xxx factorio[23019]: 975.801 Info UnparsedNetworkMessage.cpp:87: Invalid packet (type ClientToServerHeartbeat) received from xx.xx.xx.xx:61261: unknown sender

I was playing on a server and the server kept lagging however it always synced back up. This time I was riding along a belt when it de-synced, and it appears that the client and server wen't able to re-sync due to the two positions that my character resided on.
