Thank you very very much for all your testing. I'm sorry it has taken me so long to respond.
I'm glad it works much better in some cases!
Regarding note 1;
This will indeed likely be improved, but is finicky business and takes quite a lot of creative solutions to make it work in as many cases as possible at once. Hopefully there will be a way to only have one single algorithm at the end, but at the moment the way to go is definitely to add more algorithms & possible add some user-defined configurations.
Regarding note 2;
Yeah, the difference will be impossible to tell in some cases. Usually easier to see the difference on moving backgrounds or super thick text (let's say BloonsTD type of text)
I think the last issue may have been slightly improved in 0.4.8, but unfortunately it may have caused other destructive problems... and this is why we need user-defined configs...
Thanks mate!
