Rendering Issues with Sparkle Party particles on impeller #31

Open esDotDev opened 7 months ago

esDotDev commented 7 months ago

When using impeller rendering engine with the "Sparkle Party" vignette many of the particles are squares when they should be sparkles.

This vignette uses the ImageShader and drawVertices method backed by a spritesheet PNG. https://github.com/gskinnerTeam/flutter_vignettes/blob/master/vignettes/sparkle_party/lib/particlefx/particle_fx_painter.dart https://github.com/gskinnerTeam/flutter_vignettes/blob/master/vignettes/sparkle_party/assets/sparkleparty_spritesheet_2.png
