Android Studio fails taking screenshot of device

Question

Android Studio sometimes gives the following errors when I try to take a screenshot of physical device from the Debug tab.

These errors appear on the "Dump #1" sub-tab of the Debug tab:

Usually I can work around it by restarting Android Studio but today I'm getting it more consistently.

I've also tried restarting my Mac, restarting the Nexus 5x physical device, replugging the device into a different port, and issuing the adb kill-server command. None of that helped.

Anyone know what causes this problem and how to avoid it?

Answer 1

This might be something from Android Studio 3.2. Can you update it to a newer one?

I'm using 3.2.1 (October 09, 2018) on my Mac without any problem.
