It's a shame because Sublime is one of the few pieces of software that I use on my computer on a day-to-day basis that isn't a buggy POS (besides the well-written venerable UNIX shell apps).
Firefox? Buggy. Chrome? Buggy. Any other GUI editor? Buggy. Android Studio? Buggy. XCode? Buggy. I could go on all day.
It's written in C++, too, so it's lightning fast. There's no reason UIs should be laggy in 2016 on the very highest-spec Lenovo Thinkpad mobile workstation, but that's the sad reality of anything written in Electron JS (along with zero 4K Hi-DPI support on Linux, so I have to squint to read the microscopic text on Slack, Upwork, Discord, Messenger for Desktop, Whatsie, Skype for Linux Alpha, ...).
