[0.15.11][posila] Screenshot over 16384 causes desync

[distortions864]

Title says it all... on multiplayer server, trying to take a screenshot over 16384 causes desync loop for whole server.

Well, it shouldn't work:

resolution :: Position (optional): Maximum allowed resolution is 16384x16384 (resp. 8192x8192 when anti_alias is true), but maximum recommended resolution is 4096x4096 (resp. 2048x2048)

But it shouldn't cause desyncs either:)

Thanks for the report.
Fixed for 0.15.12
