I have a project in early states, not that much content on my level. Suddenly the editor becomes very laggy when the 2d view is selected. This is somehow caused by this certain scene, since if I don't open the scene, the editor runs smoothly. After the lag starts, even newly created scenes "inherit" the lag in 2d view.
If I switch to script view, the lag also disappears instantly.
Is this a known issue? Could this be file corruption or a random bug?
