Not sure if this is the right subforum, but every now and again I experience screen tearing (usually around 1.4 of the way down the screen, but it wanders up & down a bit).
I've just noticed it whilst playing a movie under MPlayer, although once I quit MPlayer, I noticed windows were tearing on the Ambient screen too when dragged.
System is:
Mac-mini 1.5GHz/64MB VRam with 1GB Ram installed running OS2.7.
Screen settings are:
Ambient screen is 24-bit 1360x768 @60.71Hz Enhanced display is enabled. Double/triple buffered screens are enabled, "balance cpu usage between refreshing and other processes" is not enabled.
Video settings:
VO CGX_Overlay_GUI.
Vidoe file was an avi, [XVID] 720x304 12bpp 25.000fps, 2257.1kbps (275.5kBps)
Audio settings:
AO ahi_dev.
Audio 48000Hz, 2ch, s16be, 192.0kb/12.50% (ratio 24000->192000)
Audio codec [ffac3 afm: ffmpeg (FFmpeg AC-3)
Oh, and it was Star Wars (Ep4: A New Hope)

-------------------------
After a reboot, everything is fine, and the file now plays perfectly.
The system had been running probably for about a week, using mainly MPlayer and occasionally OWB. I don't remember starting any other apps, although VNC server is always running iconified, and a client had been connected during this session.
RemoteMouse was in WBStartup (but is now removed).
I'm not sure that MPlayer caused this, since it's not something I would have noticed without dragging windows or playing video files.
This screen tearing crops up every so often, but with a quick reboot it's easily fixed. I'm just wondering if there are any likely causes identified.
Alternatively, if/when this happens to me again, is there any debug info/memory usage info/task lists from system monitor/etc which would be useful for anyone to help track down the cause?
Regards
Rich
