RDP session gets killed randomly with `[TDPClient] RuntimeError: unreachable` and `[TDPClient] websocket closed with error code: 1005` about teleport

Looks almost like it's flapping between two slightly different screen sizes.

the RDP window is in full screen mode, so the browser shouldn't get resized. I get a bunch of these events, even before the disconnect, but haven't managed to track down why. in any case, i don't believe the resize events are related to this problem.

[zmb3]

I'm not so sure. You report problems starting in 15.2 which is when resize was introduced.

@uedvt359 can you try finding a stable size, such that the screen height doesn't appear to be flipping back and forth with a 1 px difference, and see if it still reproduces?

[uedvt359]

it seems that the 1px flapping is caused by alt-tabbing away while in fullscreen mode of chrome.exe --app=.... i'll see if this reproduces, but for now, i can't keep the session going long enough due to another bug (which i'll open a seperate issue about => #42349).
