When I try to paint ground textures the curser stumbles and paints extremely slow.
Anyone else have this problem? (I just noticed this after the Sept. update).
Update: I reverted back to March fixes, and it does it on that version too.

The GG paint w/ textures is #37 or so of a long list of quirky tool sets in GG Classic.
What you mean by slow and stumbly, I'm not sure, but if you select a texture from the bottom
stages of the menu squares, you have to go over the terrain multiple times in order for that
texture you selected to finally bleed through the layers of the past. I'm not sure how they where
able to achieve the behavior of this weird effect?
Also, there is a kind of partial write over of data corruption when you choose multiple textures.
If you're intention is to paint with several textures at once-- it seem to produce that also.
Sept or March?! Seems I heard it was posted in 2018 or 2017 perhaps?

I had no idea, wow. Sure, sounds like something that needs to be fixed.

Yeah, we'll see what MAX brings. It would be good if they are open to user input to see what the community thinks would be useful for terrain painting. Instead of the old 'Classic' banding which really takes the cake, they should instill a blending/ blur brush. Others like Splattering, scrubbing, plowing, stubble, donut, cube, wet brushes and more would be nice to see.

A fresh reinstall of GGC fixed my issue.
