Apple Cinema 30" an strange lines
 
1 Attachment(s)
I use the dual-DVI connector to hook a Quadro FX 4500 to the Apple 30" display @ 2560 x 1600 50Hz. I'm running RHEL 4 and using the 9746 drivers. In this confirguration (and with previous drivers) whenever pixels (in this case the depth buffer as luminance) are drawn to the screen using glDrawPixels, I get these tile lines (see below). The same code on the same machine (or others) with smaller displays does not produce lines.

The modeline for the monitor looks like this

Code:

Section "Monitor"
    Identifier    "Apple30"
    DisplaySize    640    400
    HorizSync      49.0 - 98.0
    VertRefresh    60.0
    Gamma          1.6
    ModeLine      "2560x1600" 268.0 2560 2608 2640 2720 1600 1603 1609 1646
    Option        "DPMS"
EndSection
...
Section "Screen"
    Identifier    "Screen0"
    Device        "Device0"
    Monitor        "Apple30"
    DefaultDepth    24
    Option        "Overlay" "True"
    Option        "CIOverlay" "True"
    Option        "Stereo" "0"
    Option        "SLI" "Off"
    SubSection    "Display"
        Depth      24
        Modes      "2560x1600" "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

I'm not really clear from your screenshot what the problem is. Could you elaborate or post a screenshot where the problem does not exist for comparison?

Also, please provide a means of reproducing this problem.

Thanks,
Lonni
