After the last update, I had big flashing triangles, low FPS and bad shadows.

Well that sure is one low end ..PC or.. Laptop..did you try and check your drivers for graphics by any chance? Perhaps update is required for those?

Or maybe try to tick off, Preferences > Games > Use graphics hardware for displaying maps(alpha-channels, anti-aliasing, etc.)

Try then?
This is something wrong with your graphics driver.
