running emacs 28, lsp-mode with ts-ls, doing js,jsx,ts,tsx in certain jsx files (can't figure out the pattern), the editor and the language server get out of sync very quick/easily and flycheck starts reporting all sorts of weird errors (flycheck uses LSP as checker). tried js-mode, js2-mode, rjsx-mode, all of them fail the same way. My current set-up is prelude with it's js module disabled and I've been experimenting with vanilla set-up for the modes listed above.
With tsx files I don't have any of these problems. Using pretty vanilla web-mode right now.
Where do I start hunting for the problem?
