Gnome-Layout-Switcher causes all windows to disappear in Tiling Mode...?

Tiling mode sounds cool, and the Material Shell extension seems really fleshed out, but as soon as I switch to tiling mode in gnome-layout-manager and apply it, all my windows disappear. The weird thing is that I can interact with them, but all I see is the desktop, like the windows are 100% transparent. When I show the overview, the windows show again, and for a second they show going back to their positions when leaving overview mode (that’s how I was able to see where the buttons were to get out of tiling mode).

Any idea what would cause this? Can’t find anything about it on google.
