Slow response vscode, scroll freeze, slow file navigation

[induratized]

Issue Type: Bug

Install the extension and open a JS large file ~1000LOC. Now scroll around, Cmd+Click a function to navigate to its declaration, open another such files and navigate around. Everything seems to run quite slow and this is irritating UX.

Extension version: 3.15.2 VS Code version: Code 1.69.2 (3b889b090b5ad5793f524b5d1d39fda662b96a2a, 2022-07-18T16:12:57.074Z) OS version: Darwin x64 21.2.0 Restricted Mode: No

had you test other themes

[induratized]

Other themes are working fine. I used vscode bisect feature to zero down on extensions slowing down navigation. and this beautiful theme was in the list too.

My current active list of themes working fine

[Binaryify]

have no idea now, maybe the reason is the big size theme.json, it have 2000+ lines, so many rules might cause performance issue

Slow performance with Emmet.. I have to wait a bit to create from the keyword td
