Screen tearing in all encoders sometimes #71

Closed ehfd closed 8 months ago

Reproducible both with nvh264enc and x264enc. Possibly issues with GStreamer configurations or the X11 capturer.

Happens every few dozen minutes or hours.

For now, changing the bitrate then changing it back fixes it. Disabling the compositor also might help.

Screenshots will come up.

I have been seeing some significant screen tearing here in 3D. Not seeing it nearly as much on the desktop. It looks like a classic vsync issue but I'm not convinced it is.

No longer happens as frequently, although #78 is back.
