Hi,
great piece of software, congrats. Still, I’ve noticed after updating to ST4 that, although greatly improved in usability, the LSP plugin actually increases latency a lot when typing and scrolling in modestly complex C++ files.
Few details I consider relevant: MacOS 11.4, external 4K display, ST 4113, clangd 12.0.0, hardware_acceleration=opengl
I hope his helps.
I’d say it feels like semantic popups (completion, symbol information, etc) are blocking the GUI too much. Queries to clangd in complex C++ projects (e.g. using Boost) can take long, up to hundred of milliseconds I’ve noticed in the diagnostics pane, but those should be asynchronous and not halt user interface, right?
All operations are asynchronous and don’t block the UI.
Can you try to reproduce the slowness and then click on Tools > Developer > Profile Plugins and paste the output here?

sublime.log_fps()
in that console? Then reproduce the slowness and observe whether the frame times are becoming too large.
Sorry I just realised more information needed to be gathered in order to have a significative dump. Here’s a new one after some more intense coding:

Okay. The ones that jump out to me are:
On the other hand the means and max values are all near zero. Except for this Git.git.statusbar on activated event which has a 300ms max.
Thanks, I guess I will have to spend some more time disabling/enabling plugins, in order to exactly pinpoint where performance is hurt.
Are there any known bugs for MacOS performance in the latest release?
