[FFmpeg-user] X11grab tearing

[Serge Shpikin]

Hello,

I'm trying to record some gameplay using ffmpeg. The game itself works
flawlessly but captured video has tearing in it. I have VSync turned on in
nvidia-settings and when it's turned off there and in game I can see
tearing in game, too. Is it me doing something wrong or does ffmpeg lack
some syncing capabilities? You can see command I used to record and libs
versions on this video:

I used ALSA snd-aloop module to record audio.
