Drawing the same SVG with different stroke weights causes rendering bug with P2D renderer
Description
When drawing an SVG shape (with style disabled) using the P2D renderer, the rendering will glitch if the shape is drawn more than once with a different stroke weight.
Expected Behavior
The shape should appear on the canvas at different stroke weights.
Current Behavior
The first instance of the shape appears as expected. Subsequent shapes (drawn after changing strokeWeight) are drawn with a glitched stroke.
Steps to Reproduce
- Set up sketch with P2D renderer.
- Load an SVG into a PShape and call
disableStyle()on it. - Draw the shape to the screen once, then change
strokeWeightand draw again.
Example code (from this repo with SVG file included):
PShape aSVG;
void setup() {
size(600, 300, P2D); // changing to default renderer works
aSVG = loadShape("A.svg");
aSVG.disableStyle();
}
void draw() {
background(255);
scale(3);
strokeWeight(1);
shape(aSVG); // removing this first shape works
strokeWeight(3); // removing this stroke change works
shape(aSVG, 100, 0);
}
Your Environment
- Processing version: 4.3
- Operating System and OS version: Mac OS 14.2.1 (Intel)
Workarounds
- Using the default renderer works as expected
- Drawing the shape only once (with any stroke weight) works as expected
- Drawing the shape multiple times without changing stroke weight works as expected
- Loading the same SVG into a separate PShape instance to render as the second graphic works as expected
Not sure why I can't attach images here, but you can see screenshots in the linked repo
Extra info, I tested it on windows and the same thing happens.
