reassign 825392 libgtk-3 3.20.4-1 thanks I just downgraded back to 0.22.0-4 and the bug is still there. I can still drag and drop other thing, for instance in Nemo.
So the question is: which other package could be responsible? I see that libgtk went from 3.20.3-2 to 3.20.4-1 more or less at the same time, and indeed, downgrading fixes the problem, so reassigning.
