My observation is same, never had problem with earlier releases or any
other software.
I don't use Gimp, but I think I would have noticed accidental drag and
drop for any other software. A simple mouse move ends up dragging image
from darktable or changing properties of module.
I believe chromium uses GPU behind the scenes - at least based on
command line options and other pointers in source code. That one and any
other programs I normally use don't exhibit this behavior. If mouse
button is stuck, chromium would select the region on simple mouse move.
I'll install Gimp and see if I can reproduce the problem. PC was not
heavily loaded. I had barely opened one image from film strip at the
bottom and was planning to choose one of the modules after adjusting
exposure. Moving mouse around caused exposure module to go berserk and
moved every slider. I did switch to other programs to see if I can
reproduce and if it's mouse problem with no luck.

I can confirm that I had the same behavior on my notebook around the
release of 3.6. Not sure about the exact version of dt, because at
that time I did not have much time for it. I was running xfce on
manjaro with Nvidia and OpenCL. Since then 3 things have changed: I
switched (for another reason) to gnome shell, I updated the system and
darktable to the latest version, which means master for dt, and I am
not facing that issue any more.

Have you observed the same with other programs
using opencl? I think Gimp could be a
candidate; try to keep it busy for a while and
see if that happens again. If so, my first
guess would be to blame the video driver and/or
the version of the x server. Is there a version
you could update to? Anyway, you may increase
the chances of a sensible answer posting this
question on an ubuntu list.
