Hello!,

As the title says I'm having tearing problems during video playback and I can't seem to figure out the way to fix them. Tried with vsync on and off and also setting the refresh rate under settings to the different values but I keep seeing horizontal tearing when playing 720/1080 files. I'm not sure what other settings and tweaks to try so I was hoping any of you would be able to point me in the right direction.

Details: (Hopefully they'll tell you more than they tell me XD).

The video I used to test it while debugging so you can find the appropriate pieces of code is called "Amaranthe - 1.000.000 Lightyears.mp4"



Any thoughts or pointers you guys could give me?.

Yeah, that's one of the couple of guides I followed when installing everything. Tried the bits with the aticonfig and no luck and I didn't try to upgrade the fglrx drivers because the builddate on my system seems pretty recent.

Wanted to get some extra opinions before trying to reinstall the video drivers and potentially messing everything up even worse.

Hint: Follow one guide, not 2 or more.

Second hint: www.openelec.tv install the Generic x64 version to an USB stick and see what you can get.

I know this is not really helpful but just a comment. I had a similar problem that I could never solve. I had a Zotac Nano AD12-U which has an AMD Radeon HD 7340. I could never get rid of the tearing no matter how many things I tried. I installed XBMCBuntu, Ubuntu with Unity 2D, Ubuntu 10.X (I had a CD lying around and thought it was worth the shot), Lubuntu 12.10, Linux Mint 14 with both Cinnamon and Mate and on all of them I had the same problem. I followed that same guide from above and also many others to no avail.

I know somebody that has the very same PC with Windows on it and didn't have an issue so that just confirmed to me that it was an issue with the AMD drivers in Linux. In the end, I sold that PC and bought another Zotac (ID83-U) with an Intel GPU and haven't had an issue. I have it running on Linux Mint 15 with KDE and it works like a champ. I don't boot straight to XBMC because I like to use the desktop some times since the PC is also performing some server duties but I do have it set up to start XBMC when the desktop comes up.
