Issue with studio GUI when loading in or opening window, bugged scrolling bar

Whenever I open roblox studio or open the window after I minimize is, there is a chance of this weird glitched scrolling bar near the file button

Its a glitch, I can click through it and I have to restart studio to get it off, but it comes back later. This has been happening for a while now. Can I have help on how to stop this from happening? It blocks the undo and redo buttons, and if I restart studio I lose my undo and redo progress so its not good.
