Hello people! I'm super-happy that my hack could help others to make their pens work correctly with blender! I don't know how to implement a clean solution which would let the mouse keep working. I still think that setting the pressure level to 0 at every release might work, but unfortunately I couldn't find out how to do that. I'd be even more happy if the real devs could find out a solution that helps everybody with not-wacom tablets to be using the GP, as a lot of other blender users might be working off finacial constraints. Let's hope everybody will be happily drawing very soon. Best regards everybody!

@Joshua Leung (aligorith) @venomgfx Guys thank you so much for the help! Surprisingly everything was exactly like I expected: Setting the default value to 0f solves the problem for the pen input but disables the possibility to draw with the mouse. I will now go to try to find the solution in the release event. I AM SO HAPPY!!!! XD demonstration: https://youtu.be/xkWECtX-ORs

@Joshua Leung (aligorith) so I started blender with the --log-events flag and with that I could confirm your theory about the missing pressure information on the release event. It´s really weird that it just happens so randomly. I made another short video demonstrating whats happening with the console open: https://youtu.be/LRnzfMrVwmU

@venomgfx yeah seeing nothing in this situation is exactly what I need! :) Obviously the pressure data is recieved correctly during the brush stroke, since I can draw perfectly fine up to the moment I lift the pen (this is where it creates these ugly full-pressure dots). Joshua´s theory was that the pen-up event of my tablet driver doesn´t include any pressure information (where it should be 0), so I thought if I have a default pen pressure of 0f everything should be fine, because as soon as I start drawing the value should change to something positive. Please let me know if I my logic is wrong. I got my very limited knowledge about input managment by building a few game prototypes over the last year, so this is how I would try to hack the problem if it was occuring in one of my games
@YAFU (YAFU) the device is basicly a standard pen digitizer display, so there´s no OS running on the device itself. It´s basicly the poor-man´s cintique from china. considering the price difference it´s a really neat piece of hardware and it would be a shame if it was unusable with GP. I will check out how it performs in the other modes!

I am super-excited about all the awesome work on 2.8 and its recent inclusion of the grease pencil branch. I am already having lots of fun with 2.8 (I also already got some actual work done with it) but unfortunately this bug has carried over and is still so annoying that the grease pencil is basicly useless with my current set-up. I have pen pressure working in Photoshop, Illustrator, Artrage, Krita etc. - so I am pretty confident that blender is causing the issue. I am not really a developer, but I´d like to help you with fixing this - I also could imagine that lots of blender users would love to successfully use their non-wacom tablets with blender.
