SelectTasksLabel2=You appear to have a Mesa3D OPENGL32.DLL file installed in your Aegisub directory. This file has previously helped make video display more stable, but is no longer needed because Aegisub's code has been made more robust.%nThis file will be removed by default, but if you want to keep it you can unselect the option below.
