P: If a 'multiply' layer is at the top of my layer stack, moving a layer beneath it doesn't work

[chrisell99]

Photoshop v24.7, Windows 10. 

Note: this did not happen in the previous version.

The attached movie shows the problem. The top-most layer in my layer stack is a multiply layer - it has the UV's on it for a 3D model I'm working on. If I pick and drag anything around in the layers beneath this multiply layer, everything gets corrupted and does not revert to a 'clean' document view until I hide and then unhide the top-most multiply layer. It seems to be provoked by the presence of text layers.

It is still happening here with v25.0 using an RTX3090 24GB VRAM and Studio driver 531.61*

Sames steps as earlier to replicate it :

Create an 8 bit RGB file (must be 8 bit - the glitch does not happen in 16 bit), 512x512 px, with just 3 layers :

Lower layer : Background filled with 50% grey,

Middle layer Text

Upper Layer filled with a light grey set to multiply.

Moving the text layer around caused on screen glitches.

*I also updated the GPU driver to the latest Studio driver which is 546.01 released today using a clean install. The issue still remains.

@chrisell99 , thanks to @davescm , I got it to misbehave. Turning off GPU compositing (in Advanced Performance preferences) corrected the issue for me; does that work for you?

I will write up a bug on this; thank you for sticking with me!

[chrisell99]

@Mark.Dahm Aha - yeah that fixed it. I'd actually been into the performance prefs before and tried disabling "multithreaded compositing" and it made no difference. I didn't go down into the GPU advanced settings. 

At least I have a workaround now but that's definitely some weirdo bug that could do with fixing. Thanks!

I'm getting this exact same issue that @chrisell99 has been describing and turning off GPU compositing worked for me. Cheers guys!
