It's noteworthy that the flickering issue does not occur with other window managers such as Ubuntu or Ubuntu X11 or i3. Additionally, after disabling 3D, the application windows turned transparent, displaying only a slim frame around them.

I tried regolith-compositor-xcompmgr and that seemed to deal with the issue for now.
