Preview grid drawn incorrect

[Frederic Da Vitoria]

2012.0.0.8644d58bc334 on Windows 7 64 bits

In the preview window, Panini General projection, when fiddling with the "Cmpr." setting, the image gets covered with blue lines so that the preview is nearly impossible. The blue lines return to normal if the Cmpr setting is restored to 100. This problem does not happen when changing the other settings.

I can't reproduce this issue.
It could be an issue if your special project. Could you provide the pto file where this happens?
But I assume it is related to your graphic system (graphic card + driver). Maybe updating the driver could resolve it. This would be something which is outside of our control.

It could definitely be the graphic card. This is a new laptop and I already had strange things happening. I have an Intel graphics board. I'll test this on my other laptop which has an nvidia board and I'll report back.

Adding the pto file

I tested with your pto file. No problem here, no blue lines. So it seems a problem with your graphic system.

Same problem on my Vista 32 / nvidia GeForce 9300M GS as on my Seven 64 / Intel HD Graphics 4000. I found out where those lines come from : the Grid checkbox in the first Preview tab. At least I can get rid of them, which means there is an easy work around. Same issue in 2011.4.0, so it's not a new bug.

Okay. Confirmed. Also triplane and orthographic projection (maybe an other issue) are affected.
