GUI corner radius artifacts

Questions
1

I have a repro PG:
PGDemo | Babylon.js Playground (babylonjs-playground.com)

This is likely a bug, but want to make sure I haven’t done something that is not supported. Is there a way to avoid these screen artifacts or am I tripping out? Notice tracer dots remain (same behaviour 4.2 and latest 5.0):
gui-artifact

I remember having bugs like this when I wasn’t repainting enough of the screen (invalidate rect) when I used to write windows controls… yikes! If you scroll back left it will erase the artifacts, so that’s what made me think of that…

You are right looks like the texture is not cleared big enough !!! like 0.5 px or smthg of the sort.

You can setup advancedTexture.useInvalidateRectOptimization = false; https://www.babylonjs-playground.com/#3VMTI9#592

@Deltakosh might have an idea but I guess the rounded circle antialiased so it is reaching past the rect we should draw in (a shame there is no scissor rect in canvas2d ;-))?
