With this option selected device bitmaps (off-screen video memory) are used.

Applications can store bitmaps, which are not longer displayed but should be recalled quickly in
the video memory (off-screen video memory). If you experience errors as display corruption or
crashes and suspect that they could be related to the usage of device bitmaps or to the display
driver in general, turn this option off.
The simplest possibility to bypass all conflicts in storage management is to deactivate the use of
device bitmaps. However, this will cause a decrease of graphic performance in most cases.
In general the following simple rule brings good results: For all resolutions smaller than
1600×1200, 32 bpp use device bitmaps else do not use device bitmaps.
