For some reason in the level editor, whenever I place, select, or finish resizing a face of an object, the page sleeps for a few seconds. It depends on how many objects there are. When I work on xzyop-saw, the delay is more than 5-7 seconds. It's really annoying and makes it take longer to edit it.
Also, when i pick a trigger action, it lags for one second (on xzyop-saw). I don't know why this happens. (Maybe because of the outline?)
EDIT: it also happens when i de-select an object
EDIT: it becomes more laggy when i place more objects
