Which operating system? Which model of Monoprice tablet? Which version of the driver, if you're using Windows? Which version of Krita?

I'm also a Monoprice user, and I don't get Pen Pressure detection if another program is interacting with the canvas or application somehow... at least, that is what I think is happening. More testing is needed.

If no program is affecting Krita, the pen pressure works perfectly fine, however there are some other issues as noted in another topic.

My specs:

Krita version: 3.0 (git f0cbffc)
Link to the tablet model: http://www.monoprice.com/Product?c_id=1 ... 1&format=2
Link to tablet driver: http://www.uc-logic.com/index.php?lang= ... ort&cid=17 1st option, seeing as I'm on Windows 7
I'm on Windows 7, 64bit, Service Pack 1

...
However, I am able to stream with no pressure sensitivity issues when I use Krita 2.9 animation editor beta build and OBS Studio, so long as I have OpenGL disabled.

Why would OBS Studio choose to disable the tablet driver if Krita 3.0 is open, but not for Krita 2.9? Is it possible that the tablet driver is being disabled by Krita 3.0 somehow if another application is interacting with it either directly or indirectly?

I run Windows 10, have Krita 3.0 and my drivers for the monoprice tablet are completely up to date. I use a 12x9 graphics tablet that they dont sell anymore.

I tested a few cases and found something interesting.

If I have Krita 3.0 open, the following programs cause the pressure sensitivity to no longer be detected:

OBS Studio (doesn't require a restart of Krita 3.0 - the pressure sensitivity returns in a couple of seconds after closing OBS Studio)
Krita 2.9.10 ae beta (doesn't require a restart of Krita 3.0 - the pressure sensitivity returns in a couple of seconds after closing Krita 2.9.10 ae beta)
GIMP 2.8 (requires restarting Krita 3.0 for pressure sensitivity to return after closing GIMP 2.8 )
Inkscape (requires restarting Krita 3.0 for pressure sensitivity to return after closing Inkscape)
GraphicsGale (pressure sensitivity is lost ONLY AFTER a new document is made or interaction with its canvas is possible. Requires restarting Krita 3.0 for pressure sensitivity to return after closing GraphicsGale)

I don't have these issues with Krita 2.9 ae beta when undergoing the same tests, of course replacing Krita 2.9 ae beta from the list with 3.0 in this case.

There is something really wrong with that driver... If I use a wacom, OBS and Krita work absolutely fine together, otherwise I couldn't have streamed on Twitch!
