MacBook: Mission Control thumbnails transparent after update

Hi! I installed the most recent version of MacOS, Tahoe 26.2 yesterday, on my Macbook m5 pro.

Now, when I do the gesture with three fingers up the trackpad to show all desktops (I think it's called Mission Control?) I see the thumbnails show only a transparent view, and no content is visible, until I switched to each one of the desktops, and then the content is displayed again.

See picture below, all the desktops have windows opened, but I only see transparent boxes. The first desktop is active, so the content there is visible.

I had to take a picture with my telephone because a screenshot of the screen would actually show the content, even if the content is not visible to me.

Does anyone know if this is a known bug, or a "feature"? Any way to bring this back to the old version, where I see the previsualization of the windows on each Desktop?
