Update of bug #20822 (project mypaint):
Status: In Progress => Ready For Test
Assigned to: martinxyz => achadwick

Follow-up Comment #13:
There has been no movement on the GTK bug, so I've implemented capturing the
missing events as a GDK event filter. I'm now getting up to 200 events per
second now and smooth lines with my Intuos5.
https://gitorious.org/mypaint/achadwick-mypaint/commits/eventhack-wip
The code will only work on X11 at present, but compilation and runtime is
suitably conditional.
+verbatim-
$ cd path/to/my/mypaint/clone
$ scons --clean
$ git remote add achadwick git://gitorious.org/mypaint/achadwick-mypaint.git
$ git fetch achadwick
$ git co -b eventhack-wip achadwick/eventhack-wip
$ scons
$ MYPAINT_DEBUG=1 ./mypaint -c /tmp/cfgtmp_evhack
[...]
DEBUG: gui.canvasevent: Adding evhack filter (<TiledDrawWidget object

Please can everyone test and report the speeds they get for continuous
scribbles when running with MYPAINT_DEBUG turned on? Thanks.
Commit 451ca93 in that branch is a good point to contrast it against if you
think you're getting no improvement.
