I don’t know how to make this glitch happen, it decided to happen randomly for me after placing a canvas on top of a wood panel and then removing the wood panel.
As you can see, there are two info boxes shown on screen. One for a canvas, and one for a Panel Quarter Wood.
The Panel Quarter Wood box decides to not go away. Moving the mouse around does not make it disappear.
It’s stuck on screen even if I stop holding down Q, it follows my mouse movement.
Hopefully this bug report will be of some use.
