Pen lag/deadzone on Surface pro 2017 in Zbrush

After a LOT of trying and digging I figured out what the problem is and the answer is... its not a problem, but a windows feature and its present on any PC, Laptop or tablet that runs it at all times, even if you`re using a mouse.

So what is it? Well, its a snapping "feature" windows has that snaps whatever youre trying to hold and drag to the cursors original location. Once you live the "deadzone" area, whatever youre trying to drag will move to your where your cursor currently is at. I figured this out after opening Zbrush`s infos and noticing that it was in fact recognizing every touch and action I was doing with my surface pen and that not only the "lag" would happen when I was trying to sculpt, but also anywhere else on the screen, including interacting with the UI.

If you wanna get to this conclusion yourself too, try opening your desktop on your surface and then try holding and dragging a folder around. Youll notice right away that the same thing that happens on zbrush also happens on your desktop. Your folder will stay in place even though the pointer under your tablets pen wont and then itll jump to the pointers location once it moves out of the "deadzone".

Anyways, I figured this could shine some light on this problem since now we know its not software specific, but a windows thing. Personally i imagine thats one of the things that companies like Wacom fix when they release drivers for their own tablets, but since Zbrush is not as globaly used as software like photoshop and pixologic isn`t as big as Adobe, no driver has been done to get around it.

Sadly I dont know how to fix it yet though, but Ill post it hear if I find out.

I wanted to post an update on this issue.

Ive been making some progress on debugging this. It seems like this isnt actually a bug, but a windows feature. Its a height and width setting for dragging that exists to prevent you from accidentally moving stuff and making copies of files. So far Ive been able to find out how to freely change those settings, but it only seems to change anything when I`m using a mouse, so I imagine the drag settings for the Pen are kept separated from it.

If you wanna try it yourself, execute regedit by writting "regedit" on your windows search bar, then open HKEY_CURRENT_USER > Control Panel > Desktop and change the DragHeight and DragWidth to whatever value you want (the default should be 4).

I`ve faved this page so i can keep updating you if I find anything else. :)

Hi Luiz,

Sorry for the late reply but thank you very much for the information.

Looks like you hit the nail on the head, I'm very happy we now at least now what the problem is.

It's amazing to me that something as simple as this can make the whole device close to unusable for me. 

If we(/you) cannot find the DragHeight and DragWidth for the pen I guess to only solution would be to wait for microsoft to fix it in an update?

I remember seeing a thread about the exact same issue with photoshop but that got fixed after a Windows update...

Did you get around to using Feedback Hub app to report the problem as a possible bug? I think you coud explain the problem more clearly then me at this point. I can then make sure I "upvote" your report 

Thanks again!

Hey guys!

I have exactly the same issue in zbrush on my surface and it has been super frustrating. Thanks so much for digging deeper into this, seemed pretty clear that it had something to do with click and drag etc. 

Would really love a windows fix for this so it would be fixed once and for all!!

Will try and make an entry in the feedback hub if that helps

Is there still no fix for that problem?!
