video issue with external monitor

[namethisfile]

hi guys,

i have noticed a video glitch that is disconcerting with my mid-2010 macbook pro that is connected to an external 19" benq lcd monitor via mini-display to dvi adapter. the issue seems to be more of a nuisance than anything else since it only occurs momentarily when i am dragging a window to the external monitor or if the windowed application is floating across the two monitors such as shown on the photo below:

the glitch disappears if i move and/or extend the window farther out.

is this an issue that i should be concerned about? or just an annoying glitch?

Have your mbp a full-body test with pressing D before the grey apple logo shows up.

I've also got a mid-2010 mbp, mc371, whose mb has been exchanged twice due to graphic card issues. So what I want to tell you is that issues exist but we cannot tell if it happened on your mbp unless you have it tested.
