Graphics and text disappear when editing

Hello,

I urgently need help

When I move a textbox or want to edit the text, the text becomes invisible, I have to hide the layer and show it again to see the text. But I can't edit the text if I can't see what I'm doing.

The same with the graphics. If I move them by just one millimeter, the area turns white, the image is no longer visible and I have to hide the layer and show it again to be able to see it.

And I automatically have the frame around each graphic to transform it. This cannot be removed either.

I have uninstalled and reinstalled the program. It has not helped.

I urgently need advice.
