I’m running a clean install of Windows 8.1 and a clean install of Sublime Text 3.
After a few minutes of working in Sublime, using ctrl-backspace starts inserting a DEL character (0x7F) after removing a word. This character is completely invisible, but can be deleted by just using backspace. Heck, I can even copy and paste it (although because it is invisible, nothing visually changes. I just have X copies of a character that screws up my code).
If I restart Sublime, it behaves normally for a while.
The only package I’m using is SFTP, but it only does something when I save, not while I edit.
Any ideas?
