UPDATE: Found that CodeGlance plugin (http://plugins.jetbrains.com/plugin/7275 ) is causing the issue.
After updating to 2016.2, whenever I try to switch between open tabs/files (by default Ctrl + Tab shortcut) there's a huge lag, around 4-5s - and sometimes it even hanged the java process, forcing me to kill it.
This seems to happen only on large projects.
I've experienced it first right after updating 2016.1 > 2016.2, then on this first "lagged session" - which lasted for almost a minute - WebStorm itself informed me that vmoptions (from ~/.WebStorm2016.2/webstorm64.vmoptions) needed tweaking. I had that done for 2016.1 but it seems something changed/reset for 2016.2. I changed it again, with -Xmx2048m but only that. It seems to be better, but it still lags and it's really becoming an annoyance.
Anyone with something similar? Any tips on what I should try or how I could debug this? Thanks.
Note, system specs:
- updated Linux Lubuntu 16.04
- WebStorm using built-in openjsdk (1.8.0_76-release)
- 12GB RAM (usually 50%+ free)
