screenshot

When trying to take a screenshot of a maximized Chromium window (CSD mode), the resulting screenshot is cropped to the size Chromium had _before_ maximization. See attached screenshot (note round corners).

This only affects 'window' screenshots, not whole-screen.

chromium ~53.x
mutter ~3.20.x/3.21.x

What are your steps to take a screenshot?

I usually call gnome-shell's ScreenshotWindow() via D-Bus (that is, my screenshot-and-imgur script does).

(The script is at https://github.com/grawity/hacks/blob/master/desktop/cap)

Short version: sleep 3 && gdbus call -e -d org.gnome.Shell -o /org/gnome/Shell/Screenshot -m org.gnome.Shell.Screenshot.ScreenshotWindow true true true /tmp/shot.png

Just verified that Alt+PrintScreen is affected, too. (External tools such as 'maim' aren't.)

Also, forgot to mention – this is regular X11 (not Wayland/Xwayland).

I think this is a chrome bug, see https://bugs.chromium.org/p/chromium/issues/detail?id=641318
Comment 5 Mantas Mikulėnas (grawity) 2016-09-14 20:10:14 UTC 
That seems very similar. Though in my case the window _is_ usually redrawn:

 - When I maximize Chrome, the whole window is fully drawn and usable, just not *screenshotable* (not even after using it for a while).

 - When I open the overview, Chrome does look 'cropped' for ~0.2sec but quickly flickers to regular (the same is particularly noticeable in the workspaces side panel).
