>Description:
	I know it sounds idiotic, but from the available evidence I
	can't really draw another conclusion.

	This is what I see:

	In editors/abiword, net/transmission-gtk, and net/wireshark I
	see similar mouse problems. These are all gtk3 programs. I only
	see the problems on my floortop-cum-server, not on my laptop.
	Both computers have identical software versions installed (not
	all the same packages on both, though) self-built from
	pkgsrc-2016Q1. The hardware, and in particular graphics
	hardware, differs. The laptiop has Intel graphics (i915), the
	floortop has Radeon.

	The problems are as follows. Clicking on a GUI element in a
	window of the mentioned programs works only once or a very few
	times. After that, clicks are ignored, and hovering over buttons
	also has no feedback effect (when it should have).

	In Abiword, clicking on text to place the caret makes the other
	GUI elements insensitive, and drag-selecting doesn't work. I
	also saw this in a text field in transmission-gtk. (There is one
	when creating a new torrent.)

	Tabs (to select different tabbed panes) sometimes highlight when
	hovered over even if they don't work when clicked.
	
	In some cases (but not all; wireshark seems extra-stubborn)
	switching to another workspace (with ctwm) and back temporarly
	"fixes" the problem. Iconify and de-iconify may also work (but
	in fewer cases).

	In transmission-gtk, I see sometimes that if I click on
	something, the focus still seems to be with the last thing that
	I clicked successfully, and it clicks that button again (even
	though the mouse is somewhere totally different).

	Possibly related is Calibre: although this is a Qt5 program, it
	also shows different mouse behaviour on the floortop. If I click
	once on some text in the ebook-viewer or the ebook-editor, it
	selects the whole paragraph (this normally requires a
	triple-click). Also, when starting up (locally), it complains:
	libGL error: unable to load driver: r600_dri.so
	libGL error: driver pointer missing
	libGL error: failed to load driver: r600
	libGL error: unable to load driver: swrast_dri.so
	libGL error: failed to load driver: swrast

	It seems to be the display server that makes the difference:
	running on the laptop with the floortop as display is broken.
	But when running Abiword remotely, displaying on the laptop, it
	complains:
	libGL error: failed to authenticate magic 89
	libGL error: failed to load driver: i965
	libGL error: unable to load driver: swrast_dri.so
	libGL error: failed to load driver: swrast
	but still seems to work. (i965 would be the hardware of the
	display).

	Especially given the data point regarding Calibre, the only real
	difference I see between working and non-working is the
	graphical hardware.  But I can't myself really believe that
	*output* peripherals would have an influence to break a very
	different *input* peripheral.

	This is a sort-of continuation of PR pkg/50320, which can be
	closed.
