[Bug 1966376] Re: Video playback always results in lines across the screen

2022-03-27 Thread Daniel van Vugt
Ah yes, it's just tearing. That's a bug in XFCE. You generally won't
experience such problems if you use regular Ubuntu with GNOME.

** Summary changed:

- Video playback always results in lines across the screen
+ Video playback always results screen tearing

** Package changed: vlc (Ubuntu) => xfwm4 (Ubuntu)

** Summary changed:

- Video playback always results screen tearing
+ [XFCE] Video playback always results screen tearing

[Bug 1966376] Re: Video playback always results in lines across the screen

2022-03-26 Thread Brandon Snider
The screenshot looks a lot like screen tearing. This occurs when the
frame rates of the window manager and video are not synchronized,
resulting in parts of multiple frames being drawn over each other.

I would certainly confirm that your window manager is set to 'sync to
vblank' or 'vsync' before taking any other steps. Your monitor is
probably refreshing at 60hz, although gaming monitors can be different.
The XFCE window manager needs to redraw at that same rate. That would
fix the tearing issue, although at 60hz you'd still have judder on any
video whose frame rate doesn't divide evenly into 60.
