I'm looking for a list of drawbacks to disabling offscreen bitmaps via

SYS( 602, 0 )

VFP help claims that certain capabilities such as ThisForm.Line() will not work in this configuration. Is there a more comprehensive list of features that DON'T work when offscreen bitmaps are disabled?

Bottom line: How wise (safe) is it to disable offscreen bitmaps by default?

Two advantages to disabling offscreen bitmaps:

1. This appears (based on limited testing) to fix the problem where transparent label controls get bolder and bolder during periods of form updates.

2. Offscreen bitmaps may improve the performance of Terminal Server applications.
