Photoshop cc 2019 Brush Lag and Bugs

Hey guys, after updating to PS CC2019 I'm having a ton of issues with the brush tool.

1. After I make multiple consecutive brush strokes photoshop cant seem to quite keep up, if I make 5 brush strokes in rapid succession the first one may appear in real time but they rapidly begin to fall behind where my cursor actually is. This does not happen in cc2018 where i'm using the exact same brush on the same document size. These are simple round brushes on small documents, I'm really not pushing it. (This may have improved with a preference reset its hard to tell)

2. It seems to occasionally (every 3rd to 5th input) skip a brushstroke, making only a single low opacity circle or no mark at all without drawing the rest of the line. I can scrub the cursor across the document at full pressure and it makes no mark till I lift the pen off the tablet to make a new mark.

3. If I hold a brushstroke for any more than a second or two I get a busy cursor (a ring of rotating dots) this happens no matter if Im using my mouse or the wacom. It no longer allows me to see the brush tip shape but will continue to make the brush stroke just fine. This happens no matter how small the document or how simple the brush.

To clarify I have reset my photoshop preferences repeatedly, made sure I have updated wacom drivers. These seem explicitly connected to 2019s brush engine because I can compare them side by side and not have any of these problems in 2018. Also their performance preferences are set up identically but I have tried increasing them in 2019 and it seems to make no impact. Thanks for the help!

UPDATE #2: Ok so it's actually still happening (with legacy compositing on) just more inconsistent than I thought. I'm starting to get skipped brush strokes again where I have to make the same mark multiple times to even get one to appear. The busy cursor is also back, as soon as I hold a brushstroke for more than about a second.

UPDATE: Ok so interestingly enough I can no longer recreate the issue it seems to have disappeared on it's own which is weird since I didn't do any updates or change the conditions I was operating in and I did quite a few restarts. However I did have an adobe employee on twitter suggest turning on "legacy compositing" in the performance menu. So that might help you guys who have this as a persistent issue. Let me know if it helps!

I was so hopeful when I read that suggestion (turning on legacy composting), but there has been no change for me! Huge lag on the brush, and can't generate anything except short stumpy strokes! Painting with the brush is a huge part of my job and this is crippling my work, seriously regretting this update! The transform tool changes are also pushing me to madness ha!!

I have the same problem. It shows up both when I use the magic trackpad and when I use my Wacom Bamboo tablet. Longtime user of Photoshop--since Photoshop 2.0--and I've never seen this problem before.

I‘ve got exactly the same problem as you do, and I tested it with my Magic Mouse which doesn’t lag compare to Wacom tablet. Then problem might be PS 2019 with Wacom

Interesting, when I use my mouse I can definitely recreate it but it's a little more inconsistent. But both the brush lag and busy cursor will eventually appear and the skipped brush strokes tend to happen after a long complex stroke.
