How do I fix Minecraft 1.17.1 Zoomed in display Problem?
Solution 1:
A Minecraft bug tracker expert told me that this issue is MC-218803 (which also has some other hilarious screenshots). This issue is caused by using either very old hardware or a very old graphics driver. These were technically unsupported for a long time already, but now that 1.17 requires OpenGL 3.2 or above, you really start getting extreme issues with it.
You can try updating your graphics driver. Problematically, how you do that depends very much on which graphics card you have. So first, you need to figure that out. I don't use Windows myself, but Google is always helpful:
Right click on "This PC" or "My computer".
Choose "Properties".
Now a new window will open, showing all the main specifications like RAM, CPU, Windows version, etc. Here, go to the left pane & choose "Device manager".
Now select "Display Adapter".
Here you'll get all the information regarding your graphics card.
(minimally changed from here)
Once you know the name of your graphics card, google something like "how to update [name of graphics card] drivers" and you should get instructions. If it then turns out that your graphics drivers are already up to date, you will likely not be able to play Minecraft 1.17+ on that computer.
