Just a preface: I was going to post in studio bug report but I am unable to create a post there.
Ever since I installed a ROBLOX Studio update a little bit ago, I noticed than whenever I click and hover, the selection box seem to be away from my mouse as shown in the screenshot. Not only that, but this prevents me from selecting parts with my mouse directly on it as well as trying to select/preview audio from my group in toolbox.
This bug is the result of the High DPI update on roblox studio. Other people are having the same problem. I don’t know how to fix this because it never happened to me, sorry.
To anyone with this issue, I solved the problem by going into Studio Beta Features and turning on DPI Aware. Not only will your studio have its UI / Icons changed, but play-testing the game will cause some issues with the camera. I suppose that’s the trade-off.
