Hi all. I have two monitors, one is 4k and the other is full hd. Basic - 4k. I faced that the right tray is not scrollable. That is, when I open the toolbar tabs, transform or whatever, I can’t scroll those panels down.
The solution is to switch the theme of the interface layout (These are the buttons next to the minimize or close program button.) in any direction and back to the one you need.
Hope this helps those who have the same problem.
