secco

does anybody have an idea why this appears:

When using certain nvidia cards (I tested three different brands now but all nVIDIA) there are problems with sync when the screen is rotated. 90 deg or 180 deg doesn't make a difference.

OpenGL fullscreen shows an area that isn't sync (see attached photo). 

I'm using the latest drivers (same forceware) for both of them.

The problem appeared on a 9500GT, a 8400GS and same on a QuadroFX4500.

Only on two Geforce 8600 cards (different brands) the problem doesn't appear.

All tested in one PC with the newest drivers (6.14.11.9038).

opengl-sync-flicker-problem-with-rotated-screen

you're saying when you rotate the actual physical monitor?

does it happen with any other opengl applications (or any other application in general)?

did you try enabling sync on your jit.window?

sounds like a monitor issue. i just tested with my nvidia 8800 and didn't experience any tearing.

-I tried three different monitors with the same result

-It only appears when rotated (90, -90 or 180 same result)

-sync flag for jit.window or jit.gl.render doesn't make a difference

-Any other OpenGL-Application shows this result. Not only Max/Jitter.

-It also appears when not in fullscreen but the area is smaller then. The larger the OpenGL-window, the larger the tearing area

-Without rotation everything is fine.

I hate to say it, but if other OpenGL apps are showing the same behavior then it's likely a driver/OS issue and nothing we do to Jitter will be able to fix it.

I know, I was just wondering if anybody else here had the same problem and maybe already found a solution. I'm also in contact with nVIDIA technical support but they are really slow.
