[trouble] unwanted switching tools Wacom tablet

[jpvianor]

Hi !
New on this forum and came for this trouble, I didn't found any relative threat. But ! I have this probleme on every machines, and with another same tablet.

the problem :

when using the pen, gimp switch randomly to corepen (normal mouse) tool.
sometime it keeps it until I go left, upon tools selection icons, sometimes it switches very quickly between pen/mouse tools.

tried :

• I already tryed to disconnect mouse, suspecting slow moves could have caused switching the tool for a correct reason.
  
• finger touch off
  

Stuff :

• Wacom pen&touch (2 differents)
  
• problem occurs on multiple computers
  
• W10
  
• The Gimp 2.10.22
  
• logitech mouse (if any know driver problem with)
  

I also encountered driver and classical trouble causing no pressure sense, every thing works great.

If someone have a trick or working solution, thank you  very much. It's borring me a lot and cause realy long work.

Thanks

hi !
I found a workaround -> go at left and tap in void.

It allows me to work.

Example of trouble : working great until i do "Ctrl+Z" - then it switchs to maincore's tool and have a lot of lag, gimp'cursor don't follow the pointer. just going left and tap, then it's OK.

sorry for the bump, but if someones knows why gimps switches like this, it would help. It happens on different computers and with too different tablets.

Kindly,
Vianor.

I would expect this kind of behavior if your tablet is marginal and the connection has temporary lapses. If the table flawless with other apps?

@Ofnuts : I had the trouble on many computers, Win7 and 10, differents gimp's releases and 2 different tablets, same model : bamboo pen and touch.

and it start around 2008. As an robotic guys, I use to "seek and destroy" troubles


It look like mouse moves and gimp swithes tools. But. . . .  it continues with no mouse connected.

thank you @jpvianor for the workaround. The Wacom tablet seems to send an avalanche of key commands when hovering with the pen over the surface, when the paintbrush or gradient tool is selected. Tapping the pen on the left side on an empty space stops this, but it's a workaround.

When doing another gradient, the flickering starts again. And I can only edit one point, upon lifting the pen from the surface the flickering starts again and the other gradient points cannot be edited at this time.

This behaviour only happens with Gimp. Rebelle, ArtRage, Mischief, Davinci Resolve, and all other programs work perfectly fine with the Wacom Intuos 4 L. It's an old tablet and an old pen, but they are reliable and still usable. I'll post the solution here when I found it out.

Edit:
well it seems there is no easy solution. Ink is deactivated in the Wacom driver for all programs, not only for Gimp. The flickering is reproducible with a gradient tool, editing one color. Then the flickering starts, and can be stopped with a right-click with the pen also. Possibly it is an interference with the mouse driver (M.M.O.7, old driver, no more supported) or another driver like the 3dx Ware. I don't know.
