Package: xwayland Version: 2:1.20.0-2 Followup-For: Bug #901883 Dear Maintainer,
I am able to reproduce this reliably with Firefox from experimental by going to http://example.qt.io/qt-webassembly/widgets/richtext/textedit/textedit.html Attaching gdb to Xwayland shows the same information as mentioned in https://bugs.archlinux.org/task/58705#comment169691, that is, that WriteToClient receives a negative count.
