Windows Dissapear in Mission Control (Mac OS Catalina 10.15.5)

Windows will shrink/reduce to nothing while using the Mission Control feature. This applies to both the button and the three finger gesture. No other workspaces are open, and I have attempted to both restart the system and the dock, to no success.

read com.apple.dock

only shows that

is enabled. Unfortunately, I lost track of when this first appeared. If someone could nudge me in the right direction to diagnose the issue, I could tinker.
