I have two external monitors connected to MacBook Pro 14" M1 with a notch. One monitor is 1440p in landscape position and another 1080p in portrait position. The problem is that when I start a remote session in multimonitor fullscreen mode the first monitor (1440p landscape) has the same black bar on top as a native screen on MacBook, and the remote desktop is rendered under it, so it ends up overlaying the title bars of fullscreen windows, max/min/close buttons and also tabs in browsers. It is a very uncomfortable and annoying bug. The weird thing is that the second external monitor (1080p portrait) doesn't have it.
Please fix this issue, it's quite a big productivity hit.
