[Bug]: Drawing lag when there are too many strokes
### What happened?

The issue #1247 still persists.

I'm a uni student that uses tldraw for private lessons, and in 4 people so far (my tutors, me, and another student) encountered lag issues when writing after a while on a page (after about 1000 shapes).

We are in 4 people with different machines and OS. I tried different browsers (both chrome, edge, and firefox), no change. On an android tablet, instead of a windows pc, looks like it lags a bit less, but not sure. If you're on a windows laptop instead of a desktop, it lags less if you plug in the charger.

For now we switched to Excalidraw to continue our lessons, but I really like and prefer the UI and functionalities of tldraw. Hope this bug can be fixed

### How can we reproduce the bug?

Start drawing on a page. After 1000+ shapes drawn, the writing should start to feel more and more sluggish and unresponsive.

### What browsers are you seeing the problem on?

Chrome

### Where did this happen?

The tldraw.com website
