Troubleshooting / Bugs: Theme Application Delay

I've noticed in Alpha 0.3.1.734 that there is up to a 2 second delay when applying the theme to a document when initially opening it. For example, with Intype NOT running, if I right-click on a PHP document, choose Open With Intype, the document opens but no theme is applied (except for the background color and text color); after about a 2 second delay, the theme colors/styling are applied to the document in a visual sweep from top to bottom.

If Intype is already running, the delay is reduced to less than a second, but it's still noticeable. Document length does not seem to be a factor, as I've tried it with files from 1K to 100K

When you start Intype, it must load hundreds of files from bundles folder (snippets, languages, themes). Early versions were doing this in main thread, so the application launch was delayed. In the latest versions, we have moved the loader to separate thread. The logic is to load files by types: First themes, then grammars, and snippets as last. The actual syntax highlighting will appear after grammars are loaded and compiled. However this is done only when Intype gets started. The reason for visual sweep is that the parser cannot work much faster than it is now — that’s cost of having user-defined grammars. We have some optimizations designed for the future, but for now this is how it should work.
