GPU Preview Pest – Possible Workaround with Placebo Effects

Instead of Adobe adding all nice and dany BS stuff. They should fix native core functionality. I find working, precise working, in Adobe Illustrator becoming a hustle. I cant seem to work perfect anymore using snapping and line-art preview mode, since the GPU preview mode is so hindered by issues and seeming bugs.

Its easy to say, yeah work in CPU mode. But the issue is. They have striped the, old regular, CPU of so much functionality. That working in CPU mode is now sluggish and slow. Each time i try to align a vector point or anchor point, i need to double check in CPU mode because GPU modes simple will show this random offset. It happens on lines, corners all kind of items

Thanks for confirming, Ton.

The Transform effect in placebo mode (or apparently any other (vector) effect) should do it as well, but it is important where it is located in the stacking order in the Appearance palette (specifically important if applied at the Group level or Layer level, then it has to be at the topmost position).

Have a good night.

Thanks Ton.

Sorry for maybe be a bit nitpicking, but as far as I can see you did not follow my previous post about the pathfinder operations with curved transparent objects. At least your screenshots show that you did not.

Perhaps you may want to reread what I wrote. 🙃

I would certainly set up and share a sample file, Ton.

But I would first have to know if you are actually experiencing the GPU artifacts in conjunction with transparent objects that are being treated with some Pathfinder operations.

In other words: Draw a curved path that is filled with C=0 M=100 Y=100 K=0 and set the fill's opacity to 50 %. Duplicate this path, move the duplicate such that both paths still overlap, select both and then do a Pathfinder Minus Front.

Do you then see GPU Preview artifacts at the edges of the new path created by Pathfinder (you may have to zoom in to see them)?

Ton,

of course I don't know how many different machines you have to do some more tests, but is there a chance that you are experiencing the GPU artifacts that are typically caused by Pathfinder operations in conjunction with transparent objects (somewhat pixelated artifacts at the edges of the paths)?

If so, I would provide a sample file that may demonstrate that the workaround I suggested may work at least sometimes.

The reason I'm asking is because I did some further tests and so far could reliably cure the transparent GPU pest with the placebo effects.

Thanks, Ton.

My tests were mainly based on the GPU Preview issues caused by transparent objects after using some pathfinder operations (also done with the Shape Builder tool or some other operations).

It's a hard nut to crack.

Thanks, Ton.

I was afraid that it may not work on any machine. I tested it on five different Mac machines and there it worked.

It's a pity.

Kurt, I wish you had found a workaround, but it does not work on the examples I have on my machine.

But there are many different graphics cards, it may work for some (as it obviously does for you).
