Bug description

After sending a message, when swiping to view message details, then quickly swiping back, a visual glitch occurs where a solid rectangle along with an opaque section obscures the viewport. You must exit the chat view and re-enter to restore it back to the proper state. This doesn't always occur so there might be some race-condition. This seems to have happened after the Liquid Glass changes to Signal were implemented.

Steps to reproduce

1. Send message (was able to trigger in "Note to self")
2. Immediately swipe left on message to view details
3. Quickly swipe right

Actual result: Visual glitch occurs where a solid rectangle along with an opaque section obscures the viewport.

Expected result: This bug shouldn't occur.

I had opened an issue about this as well: #6172

Unfortunately this bug still exists, and the only apparent solution is a relaunch of the app, which is quite inconvenient.
