Black bars after Windows update?

Since I updated my Windows 10 two days ago, I get black bars and blocks in my LibreOffice programs. Over Text over toolbar icons, everywhere. When I open a file it looks fine, but the more I edit the more black stuff appears. And once I save everything is covered in black blocks :

I suspect it has something to do with Windows? I have no idea, and I don’t know how to fix this…

Hello - Try disabling ‘Use OpenGL’. From menu ‘Tools->Options’ then under ‘LibreOffice->View’.

I worked, I think. Thak you!
