Redraw/overdraw bug or?

Recommended Posts

I am not entirely sure if this is a bug.

However. I will describe an oddity I am encountering.

 

I am freehand drawing with Affinity Designer 1.5.4

In the process of creating Textured Intensity Brushes - I stumbled over this odd effect (.m4v movie here):

http://www.i-toons.com/storage/iShowU-Capture-desktop.m4v

If the movie doesn't work I have attached screen shots.

screenshot_02.jpg - shows a first stroke and setting

screenshot_03.jpg - shows the first stroke being transformed by a new stroke - same Brush/changed settings.

 

What is happening:

I draw with a brush set to Stretch. Then switch the Brush to Repeat and draw a new line near or over the previous stroke.

The new line re-draws the old line with the new setting.

This works with any Brush. The effect happens only with the present chosen Brush.

 

I would expect that switching Brush setting/attributes would not change strokes already applied.

The effect is quite spectacular. 

But...

Is it a bug?

Hi Craig

 

Are you able to provide the brush in your example at all? You can PM me a link if you don;t want to share it out. I've tried this with various brush tips and I'm not able to reproduce this thus far

 

Cheers

Chris,


I appreciate your looking into the issue.


 


I am finding I can recreate the effect with the brushes attached. I can get this effect with most if not all textured intensity brushes I have created (many are shared in this forum).


 


What I am seeing:


I create a new layer. All drawing is happening in that single layer.


I draw a stroke. 


With the Brush Properties window open:


I Change the Brush Properties/Body: Stretch (or whatever the brush is set to) to Repeat. Draw again.


Sometimes the effect happens with this second stroke.


Change the setting again and draw one more line. 


Sometimes the effect doesn’t start happening til this stroke. Tho the effect happens every time with this stroke on.


 


The strokes (link below) are a couple I was working with where I wanted to be able to switch on the fly from Stretch to Repeat - without making a new brush (time saving).


I am finding I can get this effect with any Textured Intensity Brushes. Tho some (with repeating sections for instance) in the “factory” Intensity brushes that come with the application - don’t display the effect as dramatically as my examples.


 


Note: I am also seeing the Brush Properties/Body Stretch button stay highlighted even while switching settings. Not sure if this is an indication of something “sticking” when it shouldn’t be - in the settings?


 


Two example brushes (zipped) are here:

These are totally available for sharing - the effect is not restricted to these - they are just good, recent examples.


 


I uploaded another example movie here:

Hi Craig

 

Thanks for the brushes. I've been following what you said and whats in the videos with the brushes you have provided but I am still unable to get this to occur. Would you be able to provide details about your system such as OS, graphics, screen resolution as well as if you are using any like a tablet and pen?

 

Thanks

Chris,

I have two Macs and two Tablet setups that I use AD v1.5.4 on. I can reproduce the issue on both setups.

These are the specs for one machine. This is a higher end Mac setup. I will post the other setups specs this evening:

 

Hardware Overview:

 

  Model Name: iMac

  Model Identifier: iMac14,2

  Processor Name: Intel Core i5

  Processor Speed: 3.4 GHz

  Number of Processors: 1

  Total Number of Cores: 4

  L2 Cache (per Core): 256 KB

  L3 Cache: 6 MB

  Memory: 8 GB

 

System Software Overview:

 

  System Version: OS X 10.10.5 (14F2009)

  Kernel Version: Darwin 14.5.0

 

NVIDIA GeForce GTX 775M:

 

  Chipset Model: NVIDIA GeForce GTX 775M

  Type: GPU

  Bus: PCIe

  PCIe Lane Width: x16

  VRAM (Total): 2048 MB

  Vendor: NVIDIA (0x10de)

 

  Displays:

iMac:

  Display Type: LCD

  Resolution: 2560 x 1440

  Pixel Depth: 32-Bit Color (ARGB8888)

 

Wacom Tablet/Stylus:

INTUOS GD - 1218 - U(circa 2002)

Driver either:

Driver 6.1.5-2 for Mac OS X (probably this one)

or

MacOSX - Driver 6.3.15-3

 

 

Older driver for older model Intuos. The drivers control panel and info are not accessible from System Preferences. Settings have been migrated from older model Macs and are locked to those last set some time around 2009. This (the best Wacom product ever) tablet still works perfectly well with modern Adobe products - these are my benchmark for Wacom tablet performance.

 

Craig

 

 

 

Second Mac and tablet info:

 

Hardware Overview:

Model Name: Mac mini

  Model Identifier: Macmini5,1

  Processor Name: Intel Core i5

  Processor Speed: 2.3 GHz

  Number of Processors: 1

  Total Number of Cores: 2

  L2 Cache (per Core): 256 KB

  L3 Cache: 3 MB

  Memory: 8 GB

 

System Software Overview:

  System Version: OS X 10.10.5 (14F2109)

  Kernel Version: Darwin 14.5.0 

 

Intel HD Graphics 3000:

  Chipset Model: Intel HD Graphics 3000

  Type: GPU

  Bus: Built-In

  VRAM (Dynamic, Max): 512 MB

Resolution: 1920 x 1080 @ 60 Hz

  Pixel Depth: 32-Bit Color (ARGB8888)

 

 

Wacom Tablets:

XD Intuos 2 (circa 2000-ish)

GD Intuos (circa 2004-06-ish)

Note: Both of these tablets are quite old - but perform perfectly well (taking use in Adobe Photoshop as my benchmark). 

Most likely: Driver 6.1.5-2 for Mac OS X

 

Possibly: MacOSX - Driver 6.3.15-3
