I get the same error as @MaZDuR.
If you need somebody else for debugging, I have the same problem.
My CPU usage graph on shard3:
https://screeps.com/ptr/#!/room/shard2/W19S15 There is a stronghold in this room but it isn't reserved. Is this intended?
Watch Shere Khan's healer, also when going back and forth in history his rendered position isn't always equal to his real one.
@o4kapuk It's still there in FF 66.
@davaned It's in the post edit history...
@duckymirror Looks like I've been missing something... Turning off hardware accelaration gets legacy renderer speed back.
Am I missing something or has the SVG renderer been removed?
I often use the simulation and it runs a lot slower with the WebGL one (about factor 6).
@smokeman The exit tile problem is older than this update and is only present without hardware accaleration. (Firefox here too)
