Applications can store bitmaps, which are not longer displayed but should be recalled quickly in the video mem-

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.
