This is a Minecraft 20w21a bug i have seemingly found...
I use Ubuntu 18.04.4.
When I play Minecraft in full-screen, I can encouter that the names of specific controls and names of the currently applied keys... It's hard to describe... When you scroll down, they overlay the buttons above and buttons below.
The problem is also that the button which goes "unrendered" is still clickable where it "shouldnt be clickable".
This should be a very simple issue to solve. Simply do it so that these text labels render below the two patches of "dirt" at the top and bottom which cover scrolling. If necesarry, make it so that when mouse is outside of the area where controls are MEANT to stay, the control buttons cannot be clicked.
Thank you for your report!
