Comment 23 for bug 151674

Hi, sorry for this late late reply. Was really busy these past few weeks... I
had just given up hope and stuck to manually disabling the second monitor
every time I wanted to see videos (not that I actually had the time).

@ adz21c
I actually tried what you suggested with different window managers, installed
and tried both IceWM and Xfce, to no avail. Same tearing. I'm pretty sure
compositing was disabled when I was conducting my troubleshooting.

There is a possibility, that it is because we have two different monitors with
two different refresh rates. Your setup is very similar to mine. I have a
1920x1200 (59.95Hz) main monitor, and a 1280x1024 (60.02Hz) older LCD. You're
right! The tearing only appears on the larger screen!

Its still a bummer tho... I prefer to watch vids on my larger screen. But,
perhaps this is a big clue to the bug-squasher squad?

None of the suggested workarounds... uhm, work. I think I exhausted all the
methods mentioned. I basically went crazy for a week trying to fix the problem.
:P

The OpenGL method also did'nt work. I do a lot of GL programming for my real-
time rendering classes and test my games on this PC. The tearing still happens.
So, even pure, basic OpenGL applications are affected.

Besides, from what I've learned, tearing is controlled via the graphic-card
drivers and how they sync with the monitor refresh rates. So, it doesn't really
matter what software switch shenaniguns you input into your settings and the
graphic-card :P If the driver screws up the syncing, you'll get the tearing.

HTH,
