When a blueprint breakpoint is reached and you mouse over a pin to examine a variable the popup info window with all the useful state data is VERY SLOW to open for the first time. Subsequent mouse overs are usually quick to load.
Also sometimes there’s a visual glitch where the info box appears stretched and stays fixed on the screen even after ending the simulation. The only way to clear it is to either restart the editor or to restart the simulation and hit a breakpoint again then mouse over a pin to make the info box appear again. Very frustrating UX! Please fix.
Another issue with the breakpoint variable info box is when you want to expand arrays. The slightest incorrect mouse movement outside the box causes it to disappear. Perhaps there should be a slight delay before it hides again or maybe click to close?
