Blink: Mosh session on external screen hangs after iPad screen goes to sleep

[b00giZm]

Description

With an external monitor plugged in, I’ve noticed that the session on the external screen hangs/is unresponsive, after the iPad screen goes to sleep and is woken up again.

Steps to reproduce

• Connect external monitor
• Open mosh session on window on external screen
• Hit sleep/wake button
• Wake iPad
• CMD+O to window on external screen
• window is unresponsive (does also not react to Ctrl-^ .

System

• iOS 13.4 (17E255)
• Blink v13.3.219

I'm having a similar issue on the same system, iOS 13.4 17E255 and Blink v13.3.219
@b00giZm did you connect your display after you opened Blink or before?

If I open Blink with display already connected, the external display is stuck on a white "Locked" screen and never recovers. Cmd + O moves the white "Locked" display to a split-view on the main iPad screen.

If I open first and then connect a display, things work until I switch away to another app, and then switch back (after which the external screen is unresponsive as above)

Sometimes when re-opening, the iPad resprings.

I have this same issue after switching applications from and back to Blink. Does seem to be a minimum time away needed to replicate, it doesn’t happen during a quick switch.

The session on the iPad screen immediately picks up and is responsive, but the external monitor session is not responsive after a Cmd + o to switch to it.

As a workaround I found that creating and closing a new tab (Cmd + t followed by Cmd + w) on the external monitor reactivated the terminal session on the external monitor.
