Hello, I'm an hobbyist Krita user which has recently updated to Krita 3.1.1.
When I first used it, right after updating it, I realized that the software didn't recognize the pressure of the pen (I tried ALL the brushes, and still nothing happened.). I tried to restart my computer, change the pressure settings on both Krita and the Wacom driver, reinstall the software multiple times, but still it didn't recognize the pen. Which is strange, since all the others tablet properties (like the pen's buttons) were recognized and work well, like in the previous version.
Thanks for your help!

Did you try reinstalling the driver? Sometimes windows updates mess up the driver. Furthermore, check if there isn't any security software or mouse enhancement software(such as razer's) interfering with your tablet.

I just want to add some info about Wacom intuos. This may be useful for devs and also others who uses Wacom.

Right now i am using Wacom Intous CTL-480 with driver 6.3.18-5. Everything works perfectly fine with Krita and also Ps, and Gimp.
Yesterday i updated my drivers using Wacom Desktop Center to the newest 6.3.20-3 version. After update I had pen input lag. Every time i started new stroke there was a 1 second delay. I had to revert my drivers back to 6.3.18-5. I already wrote a ticket to Wacom about that, no respone yet.

If there is somebody using same wacom as me, can you confirm if you succesfully use Wacom latest drivers with Krita?

For a few days, I've had the Wacom CTH-490K using the 6.3.12 driver on Windows 10, as installed from the CD that came with the tablet. The Wacom driver update caused problems with the pen so I reverted the driver using the CD to make it work properly again. (I mostly use Linux Mint so I rarely notice Windows problems.)

In general, I'd suggest that people try to revert any recent Wacom driver updates, in case that caused problems. Also, I'd ask if the pen works in GIMP which is always a useful test and very easy to check.

So it is not only me then. I guess Wacom skrew something with they new drivers.
