Minor graphical glitch? - flashing Box of doom

[Orakio]

I have had this problem for a while. It used to be intermittent but now seems to be there all the time. BAsically, there is a flashing box with some graphic in it to the bottom left corner which blocks the stats viewer for mouseover.

I'm not 100% sure but I think it might have something to do with skyboxes as once while making a map it wasn't there before making the skybox and was there after.

Anyone got any ideas how to get rid of that thing?

Can anyone tell me how to fix this please? I just had an infuriating game of fibra where is couldn't see what anything was because this box was in the was of the tool tip.

It's probably some (broken) LUA widget. Try to disable them one by one and see if this thing goes away.
