Thank you! It is just like you said! After disabling it, it went back to normal. I also found I have a bunch of extensions. I’m still getting the odd grid thing, I bet it is another extension.
You guys are awesome, thank you for being so quick to respond!
Keep track of things you install on your system.
Change only few things at the same time to be able to trace back what went wrong.
Also when updating/installing in the terminal, I pay attention to what packages are been updated/installed. It helps to narrow down the search after the “culprit” when/if some issue arises.
