Support screen capture from [other apps]

[squalou]

Hi,

this is probably a known limitation, I didn't find a matching issue, sorry if it's a duplicate.

Currently using for instance flameshot as a screenshot tool does not work. Did not try others. (native one works)

I get this error :

flameshot: error: Unable to capture screen
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()
flameshot: info: Screenshot aborted.

There's a "well known" Wayland trick behind this, and using Gnome for instance requires a user launching flameshot to allow screen capture every time. (Which in turn is a Gnome very annoying limitation, let people allow apps once and for all ;) )

BTW : As much as I appreciate a DE coming with decent default apps ... there will always be other apps with 'better' or different features, and I don't think there should be a race to make native cosmic screenshot tool do whatever more than what it already does. That's not the point.

Flameshot has different config for different DEs. By default it doesn't recognize Cosmic. You can set an environmental variable to trick it into thinking it's on KDE or Gnome. At that point screen shot works*.

It only screen shots one display, and has trouble with fractional scaling.

I don't know if Cosmic need to do anything to support Flameshot, or Flameshot needs to support cosmic.

flameshot supports xdg more or less fine, @hojjatabdollahi if you export sway instead of kde or gnome it works at least on my system, my display settings are below, captures both displays. XDG_SESSION_DESKTOP=sway XDG_CURRENT_DESKTOP=sway flameshot gui

so flameshot needs to support cosmic, not the other way around

➜  ~ cosmic-randr list
DP-1 (enabled)
  Model:
  Physical Size: 600 x 340 mm
  Position: 1280,0
  Scale: 150%
  Transform: normal
  Adaptive Sync: false

  Modes:
    3840x2160 @  60.000 Hz (current)
    3840x2160 @  59.997 Hz (preferred)

EDIT: also iirc the "generic wayland" support is done via grim, so once grim lands support for the new wayland capture protocols and #365 lands, there might not even be a need for flameshot to do anything different.

Thank you !

Last word if anyone wonders : I still have issues with flameshot but indeed it's on flameshot side to fix I think.

When performing a screenshot, I can then paste it on, say, gimp.
But, I cannot copy to an electron chat app, for whatever reason.

the image is not published to the right wayland buffer I'd say. (the image is not present in this clipboard manager : https://github.com/wiiznokes/clipboard-manager whereas native scrennshot taken are there)

Will open an issue on flameshot.
