This is a terrible title but I don’t know how else to describe the result here. It looks like this:
Nothing seems to bring it back to normal other than flipping around through my other tabs, when eventually and unpredictably, things will return to normal.
As you can see in the picture, I lose all menus, address bar, tabs, etc. Full screen, hide/show the window, changing apps, changing browser zoom, min/max window… all do nothing. Has happened quite a few times but it’s always unpredictable as to when/why it will happen.
