@adityaonx thanks a bunch for getting us a bit closer to solve this puzzle. however I think now we are trading the white flash issue with seeing a normal sized window growing to maximize state on startup, which is also annoying. Given what you found out I would like to take this back to the Electron issue and ask what is going on 🙏

Thanks a ton for developing the VS Code.
However, this white flash bug has created inconvenience to some of the people including me, having it while working daily with VS Code.

To come up with this workaround mentioned above, I experimented with some values which deals with electron window handler.

This white flash issue in windows electron apps comes from chromium and a fix is being discussed in the following:
(https://chromium-review.googlesource.com/c/chromium/src/+/6092335?tab=comments)
(https://issues.chromium.org/issues/41241478).

Suggestions from one of chromium dev was to add an acrylic/mica background before loading actual window.
Currently working command line that fixes white flash in Edge Stable release is "--enable-features=RemoveRedirectionBitmap".

From what I understood is if we can display a mica/acrylic background before actually displaying the loaded VS Code can replace this white window.
