DPI scaling issue with AutoCAD 2012

2012: AutoCAD framework issues when running at high DPI scaling

Issue

You are running an Autodesk 2012 product on a system whose screen resolution is scaled to 150% and you are seeing abnormalities in the standard buttons and ribbon controls including:

• A detached and floating red A (upper left corner)
• The X button to close AutoCAD (upper right corner) does not work
• Many ribbon controls do not perform as expected

Solution

Autodesk 2012 products may exhibit these issues on systems where the screen scaling is set to 150%. You can work around this by setting the screen resolution of your system to 96 DPI (or 100%).

An alternative method is to right-click on the AutoCAD icon, select the Properties settings, and select the option to "Disable display scaling on high DPI settings."

(When I tried this the Compatibility Settings where disabled and grayed out. I found that this only works for 32-bit programs and not for 64-bit programs. Too bad.)
