Description

Created attachment 8401 The desktop when GDK_SCALE=2 is set

On my laptop I have an HiDPI monitor, I have GDK_SCALE=2 set in my environment because that's the only way many applications' icons get displayed at a good size. Everything used to work fine with this setup, but since some 4.13 release many icons on the desktop are "rendered offscreen". It's like the algorithm that places them is considering a double-sized desktop. Please see the attachments.
