What is this in AutoCAD and why am I seeing it?

I don't even know what to say. This monster only shows up in one viewport, changes sizes when I zoom and changes positions when I zoom. I can't select it. One of the leaders extends into eternity. I feel disturbed.

Hi @Anonymous,

I am guessing that this is related to your graphics card. I suggest first trying to fix this by turning off Line Smoothing in GRAPHICSCONFIG. If the problem persists then try turning off hardware Acceleration.

If neither of these steps fixes the issue, please attach a sample file to a post to see if it shows up on my computer too.

Hi,

try to disable your hardware acceleration from 3Dconfig command.

Line smoothing was already off. Turning off hardware acceleration fixed it. Thank you.
