GS creates a flash when taking screenshots after kernel update in Arch Linux
Ever since the new kernel of Arch Linux arrived (kernel v5.3.6) gnome-screenshot started making a rapid blueish flash when taking a screenshot. If you watch a movie and press the button to take a screenshot, this flash bugs the movie and mpv must be restarted in order to make it work again. This flash also appears everywhere else - when taking screenshots from the browser or any other program. The method I always use is "capture the whole screen". I haven't tried the other methods but I'm almost certain that flash will be there too.
Edit: I made a video of the flash with my phone when I press PrntScrn. VID_20191015_235504.mkv
