I followed the instructions here: https://support.apple.com/en-us/HT201361

How to take a screenshot of a window Press Shift-Command-4. The pointer changes to a crosshair. Press the Space bar. The pointer changes to a camera. Move the camera over a window to highlight it. Click your mouse or trackpad. To cancel, press the Esc (Escape) key before you click. Find the screenshot as a .png file on your desktop.

But afterwards, I get a blank image (transparent everywhere). enter image description here

Has anyone seen this issue, and if so, what am I doing wrong? I am on Sierra 10.12.6

    Does this happen on a specific app or does it happen on multiple apps? – drivec May 8 '18 at 21:52
  • Version of macOS? Application you're attempting to take a screeenshot of? – Allan May 8 '18 at 21:57
  • OS version is: macOS Sierra 10.12.6 (also in the last line of question); Seems to happen to all my applications; I've tried this on: Chrome, Sublime Text, Adobe Acrobat – flow2k May 8 '18 at 22:04

    This happens only for the "Spacebar" version. If I just do Cmd+Shift+4 (no spacebar) it works fine. – flow2k May 8 '18 at 22:06
  • what is spacebar version? – jmh May 8 '18 at 22:44

This happens when a window has contents that are rendered outside the windowserver. Mostly 2d/3d, video and modelling software might do this. Some applications do it on purpose, like the Apple DVD player.

I would recommend you use the application "Grab" to take a picture of the screen, window, or selection. Grab comes with all Macs and is located in your "Utilities" folder. The Utilities folder is in with your applications.

Okay, I found out out what's causing it:

I'm using the Honer app https://github.com/puffnfresh/Honer.app, and it interferes with the screenshots, apparently. I've raised on issue about it.

    Interesting. It seems to render the contents off-screen and replace it post-processed later on after it put an overlay in place (which is what you see in the screen shot). – John Keates May 12 '18 at 1:52
