When I build this with --rounds=2, I get the following error:

  output ‘/gnu/store/2469sq8ny3f7dffx3v30y27d882hy5k4-module-import-compiled’ of ‘/gnu/store/8frm3y92vlkxjb2x0ljcrzx4qy357wv9-module-import-compiled.drv’ differs from previous round

I don't get that error when building the previous version of
gnome-tweak-tool, but I'm not sure if it indicates a problem with
gnome-tweak-tool or some other component.

I've also noticed that the tool doesn't work in a pure environment -
this occurs both before and after applying your patch:
