When the GUI is hidden and ESC is pressed the GUI is still hidden
Steps to Reproduce and Observed Behavior
Press F1 to hide GUI Press ESC to show inventory. Result -> Nothing to see, only your mouse
I can see the idea that this could be not a bug but a feature but I at least would like it more if it would then show my inventory etc
Right now, this is the only way some users can take screenshots (including myself.) I can see this being fixed if a dedicated screenshot button was introduced.
I think this is reasonable. There is also a good chance that people press F1/F2 accidentally and then don't know how to get back. Escape is the natural option and should be used for this. However instead of showing the inventory, I think it should first only revert the F1/F2 effects.
