Unusably slow? (release mode)

[osa1]

When I try the examples with cargo run --release on my high-end Linux box, both the gallery and individual demos are unusably slow.

For example, in the gallery, it takes seconds to scroll in the "table" demo. Switching between full screen and a small window size also takes many seconds.

In the demos, in the text editor examples (e.g. markdown), it takes a long time for the application to process key events. For exmaple if I press 'a' and hold, the app is simply unable to catch up with the key press events.

I know this uses the same library as Zed to render, and Zed is extremely fast and responsive on this system.

So it seems like an issue with this library? Or am I doing something wrong?

Please take a video for example.

This is the Markdown example issue (Because a large Markdown file parse need 100ms+， If we continue update when typing, it will can't finish parse when the new changed is coming).

Maybe this is a Linux issue then, because the same screen you show in your recording takes almost half a second to update after every scroll event.

I can record a video later today, but I'm not sure how interesting it's going to be. You can imagine adding half a second between frames in your video.

fwiw using 4c87c72 on Linux (fedora/Wayland) it's faster than my eyes can register
