brush line jumps away from cursor?

This same thing is happening to me, brush tool, automatically makes a long straight line before my actual drawing. I've tried all the fixes above, nothing is working... Win 10, Cintiq 22, drivers are up to date... This is pretty frustrating.

well its actually january, i just installed flash, tried painting in flash and get that weird problem....

will this be solved anytime in the future?

I'm having the same problem. I've updated to the latest version of Flash. I'm using A Wacom Intuos Small. Windows 7.

My specific problem is with the brush tool. The pressure sensitivity is not working properly. The line is created tapered on the ends but the line remains consistently thin. Often when I try to draw a line the line will jump away from the cursor and double back in towards itself in a straight line as has been demonstrated in some of these other posts. Sometimes when I change the size of the brush the line will not be tapered on the ends and will draw a very thick chunky looking line.

It might be important to note that the last update was odd, and wouldn't update unless I went into the files and changed them to _old or something like that.

This problem still exists.  Anyway to fix it? 

Same problem here.  Using Intuos4 Tablet.  Dual Screen.  Checked: 100% Small is already selected.  This is the most recent iteration of Flash Professional CC.  Just downloaded and installed today.  Reinstalled Wacom drivers and restarted = no change.   Does anyone have a better solution than "unplug it - plug it back in"?  Very frustrating.  Deadlines to meet.

UPDATE: I have uninstalled the intuos4 drivers for the tablet.   I then installed Intuos Pro drivers - restarted computer - started flash pro - then plugged in the tablet - allowed windows to install drivers - re-entered preferences - re-fixed lag issues from "hold to right click" and "swipe"  = Tablet is working fine now.  I'm not sure whether uninstalling an reinstalling drivers, switching to the pro driver, or if having flash open during windows installing the driver was what fixed the problem.   Sorry, but I'm not going back and trying to recreate the problem to figure it out.  Just happy to have it working again.    Hope this helps someone out.  I now know how infuriating it can be.

**UPDATE 2:  After switching away from flash (exported video, to work in premier) and coming back to flash, the problem has manifested again.  Sorry if I got anyone's hopes up.  Although, if you only have one thing to do in Flash you may get it to work for a while this way.   It seems ridiculous to me that this is so broken. This is practically flash's most basic/fundamental function.  I hope there is an official fix soon.

Same problem here:

using Cintiq 13HD and a laptop (ASUS N550JK-DB74T) with Windows 8

How annoying it feels to pay monthly to be fully updated only to have a useless version..

hi im having the exact same problem and its really anoying. i just got the latest version yesterday and im using it with a cintiq 13hd and my pen is a few centimeteters of  when i try to draw! the problem is not fixed and it is very frustrating. i am using it with an asus

Has anyone been able to confirm the Small-100% solution from Latha? I've run out of trial and would really rather not try buying something I'm not sure if works.

This problem has not been fixed.  It still occurs for me, making it impossible to do work.  I find it very frustrating that an item that I'm paying for is completely useless to me right now.

Here is a picture of what exactly happens.  If I start up flash with the tablet connected, it will immediately have this issue.  If I disconnect and reconnect the tablet while flash is running, the first line works normally (line "1"), then all others have the jumping problem (line "2" and "3")

Ok, I see that the Mobile package is with Flash in CC. I uninstalled and re-installed via the instructions above.  I am having the same issue. Do i need to change a setting?  Thank you.
