Pattern Preview is not starting (Photoshop 22.1.0, Windows 10)

Expected — "Once you enable Pattern Preview, you'll notice the workspace area outside of the canvas boundary will repeat the contents on the canvas".

Observing — two alert popups saying (approximately, reverse-translated):
1) "host preview only shows in OpenGL document windows"
2) "Pattern preview works best with smart objects. Transforming raster layers can lead to unexpected results".
Totally no change in the workspace area.
The menu checkbox is checked as if ok.
Turning off GPU support did not help (not sure if it should).
