Desktop flash when using Peek on Linux Mint 18.3

[grimmer-std]

I'm not sure how to reproduce it yet, but you can see an example here

but it also happens when I recorded as *.webm format.

Peek version: 1.3.1 (from Ubuntu PPA)
GTK: 3.18.9
GLib: 2.23
gifski enabled: true
OS: Linux Mint 18.3 Cinnamon 64-bit

This is usually caused by graphic driver issues. It's nothing that can be solved by Peek.

If you are using Intel graphics switching between UXA and SNA acceleration methods can help. See e.g. https://wiki.archlinux.org/index.php/Intel_graphics#AccelMethod

For Nvidia or other drivers I don't have much experience, but it was reported that changing the "Allow Flipping" setting in the NVIDIA control panel can help.

Apart from that updating your OS to a newer release can help, Mint 18 is rather old. There have been many fixes in graphics drivers since then.

I fixed it:

sudo nano /etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection

Save it and reboot or logout

Sorry for a late reply but it looks like turning "Allow Flipping" off fixed it for me but only after a reboot.
Note to myself: read the whole readme file before opening an issue.

@grimmer-std is this option available in peek or linux mint because I'm using manajro kde

[grimmer-std]

@Ashutosh-Kukreti it is available in Nvidia X Server Settings, not in peek. I never used Manjaro but if you have a Nvidia GPU it should be similar. phw already linked potential solution for issue related to built-in Intel graphics.

@grimmer-std Thank you :)
