Type of device: 2-in-1 Laptop (Dell Inspiron 7386)
Pen: Dell Active Pen – PN350M
System: Windows 11
Version: 5.1.5
Description of the issue:
Overall eraser button on a pen works, but each time I try using it often times it doesn’t erase how it ‘should’. it feels irrational.
Best I can describe is that when the pen is close to the screen only then it can register that I changed to ‘eraser’ mode. Meaning If I want to draw something and quickly delete it at best I will get just a big circle in the middle of the screen.
The eraser only works normally when I hold eraser button and click twice.
Do you mean that you have to click the button on the pen twice to make it go into eraser-tip action?
Or do you mean that you hold the pen button down, keep it down, then touch on the screen twice?
Yes, the stylus tip has to be close to the surface to be detected and for stylus button presses to be detected.
When you say “eraser mode”, do you mean the ‘eraser mode’ that krita has and the pen button is mapped to the ‘E’ key?
Or, do you mean that the stylus itself can be switched between a ‘pen tip’ and an ‘eraser tip’ by pressing one of its buttons?
Either way, until you touch the screen, the Eraser Circle brush preset outline will be at its maximum size then will go down to zero as you touch the screen and increase in size as you apply more pressure.
When you say “eraser mode”, do you mean the ‘eraser mode’ that krita has and the pen button is mapped to the ‘E’ key?
Ah, by eraser mode I meant button on a pen that changes it. When I press and hold it should change to eraser.
Do you mean that you have to click the button on the pen twice to make it go into eraser-tip action?
No, I don’t need to click it twice when I do everything slowly. The eraser seems to be working when the pen nearly touches the screen. I also tested again today and I noticed that the eraser brush just isn’t fast enough to ‘generate’ the stroke and when I release the pen, eraser just leaves a dot. Sometimes it seems that when i put the pen higher than the screen can register pen pointer and press & hold the button, eraser seems to not work.
It’s kinda hard to explain so I made a video below to showcase my issue. .
I also want to mention that Krita is the only drawing program I know that has this ‘weird’ eraser so it isn’t my pen’s issue.
Here’s a video on showing a small test of me using only pen for drawing & erasing the background. Video explains way better than text in this case.
The video is informative and well made so thank you for that.
So it’s to change the stylus into an erasing tip instead of a painting tip, by pressing and holding the button down.
Yes, unless the stylus tip is near to the screen, the laptop thinks that it has been taken away and no signal will be generated.
It’s the same with a drawing tablet and it may be that your laptop needs the stylus tip to be quite close to be able to detect it and detect what mode it’s in.
That is not surprising. The press of the button will probably need to be ‘registered’ inside the laptop by the driver and it may have problems doing that properly if the stylus tip is away from the laptop screen surface.
That is a matter for the laptop driver/software to sort out and to tell krita what is happening.
Krita works well with my double ended stylus that has a ‘pen tip’ at the pointed end and an ‘eraser tip’ at the other end. My drawing tablet and its driver detect which tip is in use and everything works.
However, it takes time for me to turn the stylus around in my hand so there may be a timing/response issue here.
Can you try this by doing things slowly to see if that affects the result?
I suggest that you keep the stylus tip close to the laptop screen.
I notice from your video that the erasing problem is not regular, it comes and goes.
That may be related to the distance of the stylus tip from the laptop screen.
Also, there seems to be an autosave in progress that keeps getting interrupted.
Can you also disable autosaving to see if that affects the behaviour in any way.
Doing it slowly works flawlessly. Except sometimes when I draw and press the eraser button and quickly release the pen above screen, it leaves a eraser dot and cancels the pen (which is kinda funny )
there seems to be autosave in progress that keeps getting interrupted.
Can you also disable autosaving to see if that affects the behaviour in any way.
Disabled for now. I don’t really feel any difference since I do these ‘tests’ that smudges whole screen for quick try and not in any bigger art piece.
However, it takes time for me to turn the stylus around in my hand so there may be a timing/response issue here.
I think that as well and it’s really kinda bad for me that it does it. Since I like to draw and quickly erase stuff that is wrong especially in base coloring process. Is there a way to reduce the delay? Or perhaps wait for another update?
I suggest that you create a Develop: Artists Feedback & Testing topic where you give a summary of the problem.
You can give a link to this topic for background information to say “this is where it all started from”.
