UI performance issue

Hi,

We have a (2.16.1) window dedicated to show a GUI. But strangely, there is a very regular and long hiccup , while nothing is happening in the scene:

What could cause this? I have attached the microprofile if it can help.

Thanks for your help!

Also, simply moving the GUI window around will significantly impact performance, even when the windows cannot be docked together. This is absolutely a *blocker* when using an IG with a pilot in the loop!

So... I dig deeper, and the spike has nothing to do with an additional window.

It's even more strange. I removed all code from our app (literally, leaving only engine->main() in main.cpp, with no system or world logic at all), removed all plugins except IG, and... the spike is still there IF there is "-sync_master 1" or the Syncker plugin.

Deceptively, I couldn't reproduce the spike on a brand new IG project with just that "-sync_master 1" (would have been too simple). So there must be something else, but as I removed all our code with a an empty world, I'm left clueless.

Edit: I removed data/.cache_textures and all data/*.cache; this somewhat reduced a bit the duration of the spike and their frequency, but they are still there. I'm really puzzled now.
