Bug 360253

(This has partial resolve on using version 3.0, but this could also help some of the people having same issue?)

I recently updated my OS to Windows 10 Pro (i had Win 8.1 Pro before). Before upgrading my krita worked perfectly with my Trust tablet. After update, the moment my pencil touched the tablet, krita stopped working and crashed (the typical windows notification). Of course Krita doesn't crash if I use mouse. I don't have another tablet to test this on, but as far as I have heard and searched information, this is issue within for example Trust tablets.

I contacted trust support, from which I got reply that drivers for 8 should work and I'm currently waiting for further reply since obviously that didn't solve my issue. If I reinstall the drivers, on first start up the pen works (seems laggy) but pressure sensitivity is gone. If I unplug and re-plug the USB, krita crashes. If I restart krita, krita crashes on the moment I use my pen.

So far I have attempted getting 3.0 prealpha build, which worked but no pressure sensitivity. I renamed the krita folder (in APPDATA) to krita.bak. That worked and I got pressure sensitivity to work. I have only tested this for few minutes so far, so I can't tell if there's further issues but I'll update if that happens. From this try, I have both krita and krita.bak -folders as a zip file, if this would be any kind of help.

I attempted renaming krita folder to krita.bak in version 2.9.11 too, but first time pressure sensitivity didn't work. I restarted krita, and I got the crash issue again.

Reproducible: Always

Steps to Reproduce:
1. Open krita version 2.9.11
2. Try to draw with your trust tablet
3. Krita stops working and crashes

Actual Results:  
Windows error message : "Krita.exe has stopped working" - Problem problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.

Expected Results:  
Draw a line.

Build 3.0 seems to work so far with additional step to make pressure sensitivity to work. Build 2.9.11 does not work with tablet.
