Chrome is slow when I have a Sublime Text 3 full screened on an external monitor. If I move the fullscreen window to the main display, the slowness goes away. It doesn’t seem to matter which display Chrome is on, or if it is full screen.
Chrome slow when ST3 is full screen on an external monitor (MacOS 10.14.6)

Sublime shouldn’t have any impact on chrome, maybe there’s a vram/ram issue? Could you try using the "gpu_window_buffer": false setting?

I’ve added that and I’ll give it a few days. The issue tends to clear up if I restart ST, and reappears some undefined time later (typically same day).
I opened activity monitor and could see my GPU usage pegged for the 10 minutes before I changed the setting. It dropped down immediately upon closing ST, has only gone as high as 70% once in the last 10 minutes. Chrome has been fine so far. ST speed seems unaffected.

Is that compute usage or vram usage? Could you see which process was causing that?

@bschaaf I believe that’s compute, but it’s not labelled. I’m not sure if there’s a way to show VRAM usage.
I set "gpu_window_buffer": false on Friday, and haven’t had any issues yet this week. ST performance isn’t noticeably different.
