[BUG] Syntax highlighting goes white at ~10KSLOC (Bld 3059)

#1

When loading large source files, at around line 8K the syntax highlighting begins to become erratic. Further on at around line 10K it goes completely white.

Below are 3 screenshots depicting the syntax highlighting issue at lines:

Do you see similar issues with ST2? ST3 seems, for performance reasons, to disable syntax colouring on very long lines; perhaps it is doing the same with very large files. Personally I would appreciate it if such “intelligence features” could be switched off, given that on some systems the performance is not a problem.

Please note this is not some kind of “performance preservation feature”. This is a bug.
