When i open my menu in Creative, sometimes a glitch happens. When I try to select an item and drag it to my hotbar, it dissapears or doesn't even select. You can see the attached video which shows the presence of this glitch. It all fixes when you close the menu, but the glitch often takes place and is very annoying.

Edit: this happens more than often. About 80% of the time I open the menu, I cant pick anything. After clicking about 20 times around the menu it finally fixes itself.
