BlurEffect quality decreases when transform scale is increased

[Auroriax]

Hiya,
I'm running into an issue where the scale of the UIBlock transform will strongly impact how good the resulting BlurEffect will look. Is there some way to render the blur effect the same way, no matter the scale of the object it's rendering to, or to configure this on the BlurEffect somehow? See images below for an example with three differently scaled blurred objects that have identical settings (outside of compensating some settings for the scale, like the Blur Radius) but with the results looking very differently, which becomes especially notable around a scale of 100.
