Screen Staining

Anonymous — Mon, 05 Mar 2018 14:19:14 GMT

Hi Everyone

We have some drawings that often "stains" (for want of a better word) that drawing as the zoom and pan commands as used. We seem this quite often, and even REGEN does not remove the stains.

Does anyone know what causes this or even how to fix? There is a screenshot attached which blots out the actual drawing due to sensitivity.

Thanks

Does it happen on drawings that are bigger than your average drawings? A video card that is struggling to keep up will do this. Hardware acceleration on or off?

See screenshot below, Hardware Accelerator is off

Apologies - this drawing is considered a medium sized drawing, certainly not one of the largest.

Definitely a graphics card problem. Try to upgrade (or downgrade) its Windows driver.

Thanks Vladimir, though how could this explain where this happens on some drawings but not others. Drawing sizes and contents are comparable.

Theoretically can depend on the visual style used in a particular drawing, or on entity types (arcs, 3d), or on the number of vectors (video/display-list memory).

Hi @Anonymous,

This update from Microsoft just became available. Can you try to install on your computer and let me know the results?
