Fresco Lag after a few hours

So, I use Adobe Fresco alot. I very much prefer it to drawing in Photoshop, the interface is quicker, the touch controls are more responsive. It's just a better place to draw.

Except.

That feeling only lasts about an hour or so. After an hour or so (a few if I'm extremely lucky and there are super limited layers), once multiple layers and strokes have been made, once groups have been grouped and blend modes have been applied multiple times... something terrible happens. It just... chokes. Suddenly, the smallest adjustment takes many seconds to apply. Zoom freezes. Brushes lag. 

There is ALWAYS a lag on eye-dropping colors, which is weird and almost like it is going online for such a simple task, but I can sort of get used to that, especially if I have a library of the colors I want to use. But once this hour or so limit is hit, the whole program is unusable.

I used to run into this a little on my iPad Pro (2017), but I chalked it up to limited ram. When I saw that Fresco was available for the Surface Studio 2, it seemed like a match made in heaven. Big screen, smooth drawing... And it is!

For about an hour. 

If I close out and get back in, sometimes that will make things better for a bit, but the problem always comes back. This is huge because, while it's more stable, drawing in Photoshop is just not as fluid as drawing in Fresco. It's just barely laggier in normal use, just a little jankier. Fresco is obviously a new and better drawing engine that works awesome with touch.

For about an hour.

Obviously, this doesn't really work for a professional environment. When I work on a book, I need to be able to work for hours at a time and really get in a flow. I need to build out layers, move sliders, copy and paste (another issue with Fresco is it's RIDICULOUS copy and pasting, the option is so buried).

I see complaints about this across devices, so it doesn't seem limited to the Surface Studio 2. 

But, speaking of the Studio 2... This shouldn't be happening at all. I have 32 gb of RAM, a tb solid state drive for a scratch disk with almost nothing stored on it (I clear off finished projects onto an archive when they're done).

PLEASE make Fresco usable for extended periods. I love the interface (besides the hidden copy paste that takes too long to use). I love the drawing engine. It's just so great.

For about an hour.
