For some reason, if you setup some storage filters, the game become very slow FPS wise, even when paused. Its only there if the filters of a storage are shown and set.

It works all perfect and without the opened flags & filters in the gui it has no effect, just a bit disturbing to use when it must go fast.

I do not can fix it without alot work because the analzyer give no hint what it is.
Also, again, it does work and there is game wise effect.

If anyone finds out or have an idea what it is, please report.
