Some applications sometimes don't have window shadows

[MadEvening1]

What Happened?

Certain applications like AudioRelay, VLC (Flatpak) and Synaptic (downloaded via apt) sometimes don't render their window shadows. I'm saying "sometimes" because the problems fixes itself after a reboot, but comes back after another.

Steps to Reproduce

1. Open any of the mentioned apps
2. Look at window decorations

Expected Behavior

All applications are meant to have proper window decorations... I guess.
