This is actually scale filter bug.

comment:2 by Jozef Chutka, 3 years ago

Hi Elon,

I wasnt even aware scale filter is being executed in this case, considering its not part of the filter chain.

Is there any workaround or even better work in progress to resolve?

thanks

Perfect, Elon. Just checked with latest build and closing as fixed, thanks.

Any chance you could have a look at #9561 or #9541 ?
