Peek: Capture flickers and captures desktop background

Created on 23 Jan 2018 · 4Comments · Source: phw/peek

Whenever I run a capture, the capture flickers and sometimes captures the desktop background despite me not clicking on anything or doing anything:

Example:
peek 2018-01-23 12-02

No idea what's wrong or how to debug it. Got this with 1.0.3 from AppImage, as well as with earlier version compiled to .deb from source.

Turning off "Allow Flipping" in nvidia-settings fixed it.

That's usually a driver issue, please the the FAQ at https://github.com/phw/peek#my-recorded-gifs-flicker-what-is-wrong

In case you are using GNOME you can also try to switch to the ffmpeg backend by running peek -b ffmpeg (if you are not using GNOME this is the default).

I can confirm, that "Allow Flipping" fixes this issue reliable for me (Nvidia GeForce GTX 750 Ti, Driver version 390.48 on Archlinux).

In case you need/want to automate this: nvidia-settings -a 'AllowFlipping=0' works for setting it. Be aware that nvidia-settings behaves rather strange, and if you open the nvidia-settings GUI after you used the above command, it will just overwrite the setting with (as far as I see) the value it had the last time the UI was opened.
