howdy, @codeanticode

issue occurs ONLY in 3.4... when using any PShader + transparent PNG's

this code works as expected: when using the shader() call

void draw() {
  background(#FF3300);
  shader(d1);
  image(img, 0, 0);
}

but if you do this... using the filter(shader) call... the transparency of the PNG does not behave as expected.

void draw() {
  background(#FF3300);
  filter(d1);
  image(img, 0, 0);
}

in most of current code examples I enjoy the flexibility of drawing with a PGraphics and using pgraphics.filter(shader) to apply what shader gets applied where... as seen below :
