Switching the 2D Drawing Hardware Acceleration off in the Work Environment, causes the currently open 2D View tab to freeze. The cursor is still responsive, but no changes appear anymore.
This issue should be fixed in the latest Update for ARCHICAD 21 (build 5010) and 20 (build 7001). Make sure you have the latest updates installed.
