Bug description

When I answer an incoming call on desktop, my phone often gets stuck with the screen on until I turn it off manually. This of course needlessly drains battery. It has been happing for the past few releases at least.

Steps to reproduce

Receive a Signal call
Answer it on the Desktop client
Actual result: The incoming call screen lingers in a blank form, keeping the screen turned on indefinitely

Expected result: The incoming call screen should terminate itself and allow the screen to turn off

Screenshots

The outline for the contact avatar can still be seen on an otherwise black screen:

Device info

Device: Unihertz Atom XL

Android version: unofficial LineageOS 17.1

Signal version: 5.25.8

App state

SMS enabled, Wi-Fi compatibility enabled, PIN locking disabled

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

Still occurs on latest version. Unfortunately I have no further information to provide unless someone requests something from me.
