Loss of brush control after selecting color on the wheel

[Zdele1]

after i pick a color from the wheel, first brushstroke losses opacity and tilt control, it acts as if i did that brushstroke with mouse instead of tablet. It happens only on the first stroke, second one is fine. Here is an example, i used the same brush and same pressure and pen tilt for both first and second strokes.

What PS version are you using?

[Zdele1]

v21.0.3, on windows 10. I installed latest build of the wheel and the issue is still happening, updating photoshop might help, but I cant do that at the moment since i'm working.

I also checked on v20.0.8 that i have installed, and it's also happening there

Unfortunately this makes the wheel usefull only as basic gamut mapping and color constructing tool at the moment, since undoing every time after even the slightest color adjustments is very slow and annoying. At the moment i use it only to select my color range and lay in basic colors of the painting, maybe do some adjustmens before moving on to another wheel.

Just to let you know that another thing that I found that fixes this issue is changing brush size before doing the first stroke. Don't know if that's helpfull or not. I will share more indept feedback of the new version in the next few days

I would like to hear your feedback on the new version but I haven't explicitly taken this issue in to account yet. Especially since it doesn't seem to be universal across platforms, so I will have to do some digging. It seems like the extension gets "focused" which causes Photoshop to lose control over the tablet driver. One way to test it would be to create a dummy CEP extension which doesn't have any functionality to see if that still causes the issue. If not, there is something in the KalleWheel extension that causes Photoshop to lose control over the tablet driver. It sounds unlikely though, which makes me think it might be harder to solve. But we'll have to see. I'm willing to do some debugging to see if we can figure it out. Let me know when the new version has been tested.

Sure I would love to help out with it, I might be able to test it ona a different machine with yet another version of photoshop too, I will let you know the results.

I don't have any similiar problem with any other extension i use, and i use a few on daily basis and few more for specific tasks- coolorus, brusherator, layerforge etc. this issue is only limited to this wheel

Also I did try to do a bit of googling since i remembered there was a lot of fuss about extensions when photoshop moved to cc2015, and found this info on an addon page

Maybe there is some problem? I'm not a programmer so i dont really know anything about it

I managed to fix the issue!

It was caused by a combination of PSuserconfig settings in text file and windows ink options.

Basically due to the pressure issues and wacom drivers in older versions i had to have PSuserconfig file which had the option UseSystemStylus set to 0 and i had disabled windows ink in wacom drivers. That was the only thing that fixed the loss of pressure in photoshop.

I of course tried disabling and enabling windows ink in wacom settings before, but it didnt do anything. But I have now removed that line from psuserconfig and enabled windows ink in drivers and it works - no more pressure or brush control loss on first stroke after selecting colors. Also photoshop and driver and windows ink incompatibility that was causing this pressure loss has since been resolved i guess, since i have normal pressure and tilt control with windows ink now - that used to be a problem for a very long time.

You can close this issue, but maybe it's worth it to leave it open, since that fix for pressure was pretty widespread, and maybe it will help some other people.

Another quick update, It would be great if this could be fixed since i had to go back and turn off windows ink again and restore psuserconfig file due to several tiny annoying issues that would pop up, such as photoshop and coolorus stopping to respond to pen input randomly. All other extensions work normally without windows ink

Update: I read onlien that photoshop 21.1.0 fixes those issues, I will try and update and see if it works better with windows ink

[Zdele1]

Small update, PS 21.1.2 breaks stylus support both when using wintab or windows ink as tablet service, so i had to revert back to 20.0.3 with wintab, meaning this bug is present again. I really hoped they finally fixed windows ink, but after all those years it's still plagued by bugs

[kbladin]

This seems to be an issue with your tablet driver and it's combination with CEP extensions (the extension type I use to develop KalleWheel). If you want to test this, one thing you could do is to remove all the content in index.html, leaving only:

<!doctype html>
<html>
</html>

Then the extension will be empty, if it still causes issues when focusing and defocusing the extension window I'm afraid it's out of my control.

[Zdele1]

It's still happening with empty extension. Just for reference i use wacom intuos pro with latest drivers, other extensions work fine. Also it works fine when i use windows ink, but photoshop just doesnt work well in general with it, there are constant pressure errors. I guess I will just wait and see if adobe will finally fix windows ink in 21.1.3 when it comes out. Photoshop on windows has had issues with it for years, using wintab is only solution, just google "no pressure photoshop" or something similiar.
