I have such a strange problem when working with Figma on the second monitor. If you expand the Figma window to the full screen (and I think that’s the way 99% of people work 😅), then the central part of the toolbar (create component, mask, etc.) stops working. When you click, nothing happens, and when you click 2 times, the Figma window goes out of full screen mode. If you move the window to the main monitor of the laptop, then everything works fine. Windows 11, the second monitor is ultra wide 29 inches.
If anyone has faced and knows what the problem is - I will be glad to help.
