I use a custom filter in pixi.js for blur https://github.com/louisatome/pixi.js/tree/dev-atomeV4/src/filters/triangleblur but when I use the filter on different objects, the texture of my biggest object overlaps on smaller objects.
After some research, I think it's linked to the temporary RenderTarget I use to apply my filter on the 2 axis.
First, it seems that the clear parameter of the function filterManager.getRenderTarget() is ignored when I read the source code of the method. But anyway, even if I manually call the clear() method of the RenderTarget at the end of the filter application the result is the same.
But if my 3 objects have different dimensions (let say 100x100, 200x200 and 400x400) in order to get a different RenderTarget for each, the rendering is OK.
Any idea ?
