Sublime text 3 as a whole is running very smoothly.
Setup
My PC’s cpu is old but still decent: Xeon W3520 , with 12 GB RAM, no SSD.
My mouse is a microsoft wireless mouse, I have no problem using it.
The project is set up to only include a few essential folders for index like /src
Most of the files are js and html files,
and it takes around 1.5 mb disk space
Problem:
It looks like a rendering issue, and it happens more often when the file has more code.
Keyboard/Mouse actions appears to be “buffered” or “stacked” with ~500ms noticeable delay.
Thus produce unwanted actions, such as:
- Switched to a wrong tab
- Highlighted an unwanted piece of code
- Dragged the tab out to a new window
- Close a tab (because the delayed click applies when my mouse cursor passes the close button)
A way to produce the behavior:
say I have 5 tabs open, each of them has more than 600 lines of code.
| Tab 1 | Tab 2 | Tab 3 | Tab 4 | Tab 5 |
Then I move the mouse cursor from Tab 1 to Tab 5 kinda fast, and click on Tab 1,2,3 and 4.
The end result would be:
- switched to tab 1
- switched to tab 2 (then oops)
- switched to tab 4
- and then: may stay in tab 4
- or: may switch to tab 5
- or: the cursor passes the “x” of tab4, and the stacked mouse action applies, closes tab 4
And the problem still exist after I limit the index workers, and limit the plugin modes…
I never had this issue before.
So… I upgraded my corporate desktop to windows 10 and upgraded sublime to the lastest dev version altogether, annnnnnd it started happening. 
Thanks!
