Hi,

Grim just grabs fully-transparent images in latest wlroots + sway (Git master).
I also just built grim from source (using the grim-git AUR package for Arch).

Am I missing something?

How do you invoke grim? Any error messages?

Works for me™.

Hmm, weird. Any of the ways which I invoke it... slurp | grim -g - /tmp/image.png or simply grim /tmp/image.png grabs a PNG image of the correct dimensions, but fully transparent. Also no error messages.

BTW, I did forget to mention, this is running on a second (external) display, not laptop's built-in display. Might that be a factor?

Can you try the screencopy example in wlroots? You can do so by compiling wlroots and then running build/examples/screencopy.

Can you try with WAYLAND_DEBUG=1? Can you check sway's logs too?

Nothing comes up in sway's logs upon running grim either, when running in verbose mode.

Damn, this is pretty weird. Since this is a wlroots issue, can you create a new issue on the wlroots tracker and link this one? Can you also include your graphics card model and the graphics driver you use?

@DawidLoubser Graphics card, driver?

Okay, so as I mentioned at the new issue swaywm/wlroots#1186, my card is a GeForce GTX 970, and I use nouveau (bad combination I know!).

Hmm. Not sure what happens here, my setup uses the same format. If you change this line to return CAIRO_FORMAT_RGB24, does it work?

That's not a good fix though. Could you open a wlroots issue about this, including a full sway debug log?
