Glicht with arcs when working with two viewports

[lais.r.f]

Hello all,

I am experiencing an annoying glitch when I work with two viewports in the Modelspace. As soon as I open a second viewport, the arcs in both viewports become "dislocated": the point where the arc begins and ends is not shown correctly. When I click the arc, the highlighted points are in the correct position, but the arc remains incorrectly shown. Regenerating doesn't solve the problem.

It seems to be just a glitch, if I return to having just one viewport, or if I print the drawing, the problem is not there. But as soon as I open a new viewport, the arcs get messed up.

I attached two images to show the problem:

1. with one viewport: arc correctly shown

2. with two viewports, arc dislocated.

Does anyone know if this is a glitch or if there's a way to fix it? 

I am using Autocad LT 2016.

Hi,

does the same happen (or does it help) if you play with that two switches in the dialog of command _GRAPHICSCONFIG:

That did solve the problem! So it's actually an issue of the video card? Wouldn't have guessed! thanks so much for the help!

Hi,

>> So it's actually an issue of the video card?

Let's say it's an issue in the communication between AutoCAD and the video card driver, updating the driver might help.
