All my models are suddenly messed up?

Suddenly , this (see picture) happened to all the models I have saved this year and past years in Google Sketchup.

They are all quite simple models, only 3D of simple rooms
I use Google Sketchup for Web-free version.
Worked perfectly fine before today, and I did not do anything for this to happen.

Any known error, or anything I can do to fix it?

Google hasn’t had anything to do with SketchUp for more than 10 years.

What operating system are you using? What web browser? What graphics card? What you show looks like a graphics driver issue.

Those look like artifacts caused by too large model extents.

Thanks for the reply! I checked my graphic card, and ended apps that use GPU, and that worked!
