Just noticed this. If there’s a selected gui and the gui is 2d, R2 is supposed to invoke a click on the gui. Instead, it invokes a click at the mouse position, which is supposed to ignore 2D guis. Click is reflected as the border flashing.
Also it fires MouseEnter, which it shouldn’t. MouseEnter is reflected by the tooltip appearing.
