TVPaint Drawing random straight lines at beginning of stroke.

Post by sac magique » 12 Mar 2018, 01:03

Hi guys

A quick query regarding a bug i keep running into.
Every time i attempt to draw circles/curves freehand i seem to get strange straight lines at the beginning of the stroke. It only occurs if i draw fast.

Does anyone know what could be causing this? It doesn't appear to be my Cintq because i don't get this problem on Photoshop or any other program. I also doubt that it is a performance problem; the bug is recreate-able at all
resolutions/file sizes.

Previously I have had a similar bug where straight lines shoot across the entire screen horizontally, though that problem doesn't seem to be occurring anymore.

The only similar forum post I can find is this viewtopic.php?f=10&t=2274
However this is dated 2008 and seems to have been resolved so i'm skeptical that it is the same issue.

Thanks,
Phil

Sorry to double post,

I was wrong, the horizontal lines problem still occurs. its just not as easy to recreate on purpose as the curved line problem - though i imagine they are related.

From time to time I've had similar anomalies. I don't use a Cintiq but I do have two monitors, side by side. I runTVPaint on the left monitor and other software on the right monitor. When I move between software on the right monitor where I use a mouse, and then move to TVPaint and use my Wacom Intuos on my left monitor, I can reproduce the same anomalies you show here by momentarily moving or even just touching my mouse while in the process of drawing lines with my stylus on the TVPaint screen. Note I am moving the mouse without pressing LMB or RMB or scroll wheel.

So, what may be happening in your case is drawing on the Cintiq may be causing slight movement in your mouse resulting in the spikes to the right side of your Cintiq.

Or maybe not... but it is something to check.

Does this happen with pen only, or with the mouse as well?

(It looks like the cursor X coordinate starts larger than the screen width.)

Thanks for the help.

Svengali was right, it seems the horizontal lines are caused by mouse input on my other monitors (caused by my desk shaking) - which is easily fixed by simply flipping/unplugging my mouse when i use TVPaint.

Unfortunately the other issue - straight lines at the beginning of a curved stroke - still remains. I have no idea what could be causing it.

It only happens with the pen.

Try going into Wacom Tablet Properties and selecting your pen, find Tip Double Click Distance and turn it off.

You can also try disabling Press and hold in Windows Flicks panel.

Open Control Panel > Hardware and Sound > Pen and Touch > Go to Pen Options tab > Press and hold > Settings > Uncheck "Enable press and hold for right-clicking" > Go to the Flicks tab > Uncheck "Use flicks to perform common actions" > Apply.

Also try opening the Wacom Tablet Properties panel again, selecting your pen, go to the Mapping tab and uncheck "Use Windows Ink" (at the bottom of the panel).

Thankyou so much! :D :D :D

That fixed it straight away. I'm ashamed i hadn't tried that myself, probably could of worked it out with a bit of trial and error.

One of the best things about TVPaint has to be the community! Really fast knowledgeable responses. I'm very impressed.

Thanks,
Phil
