Answered: Multicoloured squares when painting

tadpole3159

I'm painting a bump map and this happens, it's looks more like modern art than a bump map :P

This strange effect happens when i paint sometimes but its guaranteed to happen when I undo, and once it's there it doesn't go away either, deleting the layer just makes it worse as well

this corrupt look is even affecting my brush alphas. Any idea's whats wrong

(I'm on the latest build with a gtx 1080)

I've never seen this before. That's a new one! The first piece of advice I'll give is to ensure that you're running the latest drivers for your 1080. Also, what copy of Photoshop do you have installed, and what are the rest of your system specs?

tadpole3159

First thing I checked the graphics driver but yes I'm on the latest. I'm using cs5 but I also downloaded a demo of CC and the problem is there in both. My Pc specs: Windows 7 64-bit, Intel core I7-4930k @3.40GHz, 1080 GTX, 32 gig of RAM, 255gb SSD with 70gb free space.

here is a video of it in action

Let's try this: create a new color paint layer in the Bump channel. Don't switch channels while painting. Do you get the same results or does it work as expected?

tadpole3159

yep thats it, switching channels while painting makes this happen everytime.

tadpole3159

It really makes painting materials impossiable mind you. I'm giving up, I'll try it on my work PC tomorrow

Synaesthesia

How is it impossible to paint materials? You should be able to paint in one channel at a time using the color paint function.

tadpole3159

That one channel at a time thing only works while your still painting the mask, once you press accept on the mask you have a 50% chance it would work and the other 50% of the time sqaures would pop up. if i don't press accept and switch channel it goes to squares every time like you see above.

it's pretty much unusable right now

Synaesthesia

Ideally, we'd prevent you from switching channels while painting. Color paint layers are per-channel, they're not global paint values. This is likely why it's breaking for you.

I'm not sure why you'd have issues with the paint applying.  Are you using SUITE 2.2.1?

tadpole3159

Yea I'm using 2.2.1, fresh install as well. I could make a new video of it happening if you'd like but it's like I said, press apply and cross your fingers

Synaesthesia

Sure, that would help our programmer with figuring this out.

here you go

it happens as soon as I press the paint mask button this time around, and not even reverting the changes can stop it.
EDIT: Happens on my work PC as well

Synaesthesia

Could you also try using DynaMask on a material layer to see if this happens as well?

tadpole3159

Just updated the post above with the proper video, Is that what you wanted?

Synaesthesia

Got it. Sent off for further inspection and possible inclusion into the next patch.
