The Wacom Tablet Properties window seems to register pressure sensitivity, and other applications (such as Adobe Photoshop Elements) can register it, but Krita does not seem to be registering it. I have checked the brush settings, and it should be working. Only recently has it been starting to happen (today). It even happened in version 2.9- when I updated to 3.0, hoping the problem would be fixed by an update, it persisted. Reproducible: Always Steps to Reproduce: 1. Draw with any pen Actual Results: It produces a scribble of constant opacity and size Expected Results: Should respond differently depending on pressure settings
If from one moment to another, without changing Krita, Krita stops registering pressure, then, since Krita didn't change, it's probably not a Krita bug. It can be some kind of settings issue, or maybe you got a windows update that broke something, or windows decided that Krita shouldn't get access to the driver. The frustrating thing is that this never happens on any of my windows test devices, so I cannot figure out what can happen in windows or the wacom driver, or the permissions system that causes this problem. Some people with similar problems report that reinstalling the Wacom driver fixes the issue. There are also reports that some virus scanners or other "security" software causes similar problems.
Losing Wacom pressure sensitivity happens to me quite often, too, and has been there with Krita 2.8, 2.9 and 3.0. I haven't been able to precisely point out the reason for it, as it happens really randomly: sometimes after pc waking from sleep with Krita open, or after Krita just being open while using other software, or sometimes straight away after Krita is started, but not nearly always in any of these cases. The driver I use is an old one, from something like 2013. Had to try every driver version from newest 6.3.11 backwards to 6.3.6 make it work at all in the first place. Maybe you could try with different driver version? The older versions are all available on Wacom drivers download page.
Created attachment 104829 [details] L0Lock's Tablet log I have the same problem. And also a canvas freeze until i put my stylus out of the canvas and back in. I attached a tablet log. Here is what i did for it : - starting krita then debugview - pressing Ctrl Shift T - trying to draw on my canvas (not working) - put my stylus out of the canvas then back on it (it unfreezes the canvas) - draw with a pressure sensitive brush : but it looks like i'm in full pressure. I add that I'm with a Wacom Cintiq 13HD on Windows 10. And i have no pressure problem if i put Krita on my main screen and use my cintiq like a standard graphic tablet.
I've had it happen as well, but that usually meant I had to reset the wacom configuration. If you look at the tablet log, you can see that Krita isn't getting tablet events, probably because the tablet is confused about the monitor setup.
I tried to reset the wacom settings : ineffective. However, I maybe found a way around the problem. Kind of. Instead of "extending" my desktop to my tablet, i clone it from my main screen. It brings the pressure back, but the cursor position is completelly screwed in the canvas (not in the UI of Krita). If i just move my stylus from left to right, the cursor follows well on the UI, but while on the canvas it will accelerate, decelerate, block on the right side and finally hover the right side of the UI when i reach it with my stylus... And it's not a good solution either, working on the same screen isn't handy for me. Plus i'm left handed, so i usually rotate the tablet to be able to use the buttons and because my cable is on the left side anyway. But with the cloned screen, i'm forced to use my tablet in a right handed configuration. Still better than nothing untill someone found the final solution. I have the feeling that I'll be hard to read, I'm still not comfortable with english.

Comment on attachment 105238 [details] "choose screen resolution" window Hi ! I solved my problem ! :D Here is what I did : - start krita - create a new document -hold shit and press donw your stylus on the canvas It opens this window : https://i.imgur.com/ckEqNYP.png I had problems with Krita a few months ago, so I had manually set the screen resolution to solve these problems at that time. But curiously, it is these values that seem to have caused my current problems. Perhaps because of a change of version? Anyway, today I checked the first option (wintab) as shown in the screenshot, and since then everything works perfectly.

I have a wacom tablet. Sometimes I had this problem where the sensitivity sensor wouldn't work and I had to close krita or restart my computer. Now everytime I get in Krita it will always have the brush as if it's always on full pressure and even though I tried restarting both the app and my computer it won't do any good. I've tried other programs and it works perfectly fine.
You likely will have to reset the wacom configuration.
