Taking (fullscreen) screenshot through console freezes Pale Moon for some time

[tmpfs]

Every now and then I take a fullscreen screenshots of various websites through console, SHIFT + F2, e.g.

Code: Select all

screenshot --fullpage /tmp/palemoon_forum-2019-09-04.png

However over the years, through the various versions of Pale Moon, each time this action has caused the browser to freeze for undefined period of time, say 30 seconds or so. The question, is this issue solely mine, and if not, will it be ever fixed? As I'm writing this post and testing more taking screenshots, the browser doesn't seem to freeze so much if not all, but however the initial freezing is something undeniable for me.
