Follow-up Comment #5, bug #19229 (project mypaint):
I've got some new informations for all "pressure lost" on wacom tablets.
I've got an old Wacom Pen&Touch that I used to use on a daily basis with
mypaint (including 1.0.0) on windows (7 - 64 bits).
I recently bought a new Wacom Pen&Touch.
The old Pen&Touch is labelled CTH 460/K
The new one is labelled CTH 470/K
Here is what I observe.
First : Deleting drivers, Manually removing wintab32.dll then reinstalling
drivers doesn't change anything to the following description.
When I plug the CTH 470/K on the computer and I try to use mypaint 1.0.0, I
don't have pressure (tablet act as a mouse).
When I plug the CTH 460/K on the computer and I try to use mypaint 1.0.0, I
have pressure (tablet act as expected).
When I plug both CTH 460/K and CTH 470/K, on the computer, and I try to use
mypaint 1.0.0, pressure works on BOTH hardwares.
When I plug both CTH 460/K and CTH 470/K, on the computer, I start mypaint
1.0.0 and then I unplug the CTH 460/K, I can still use pressure on already
lauched mypaint. But I launch a new mypaint instance, the tablet act as a
mouse. If I switch between "old mypaint process" and "new mypaint process", I
have alternatively pressure and not pressure.
When I plug only CTH 470/K, and launch mypaint, pressure doesn't work. If I
plug CTH 460/K pressure still doesn't work on mypaint, but if I launch a new
mypaint process, pressure will work.
Everything said here with mypaint 1.0.0 works the same with gimp 2.8
What I deduce :
- This is probably not a mypaint 1.0.0 related problem
- This is not a Bamboo/not Bamboo, not even a Bamboo pen&touch related problem
but a Bamboo pen&touch 2010 versus Bamboo pen&touch 2012 related problem.
- I look like an initialization problem somewhere. both tablet works when ever
the process has been started when the CTH 460/K was plugged.
- The problem may concern every 2012 wacom tablet, because it look like Intuos
(who have entire different drivers) are affected the same way.
