[Linux] Highlight Active Line, poor performance

[jgato]

I know that this feature could impact in the performance of brackets.io. In my case the impact is so huge I have to disable it, it is really a pitty :(

Other Linux users are having such performance impact? In my case I am using

Ubuntu 13.04
Brackets.io sprint 36
Intel Graphic Card
CPU i5
4GB Ram

best regards,

Also noticing this on Mac and Linux. Highlighting in general causes lag, and stability is poor in general.

On Mint 16, Brackets occasionally locks up entirely (UI freezes and I have to pkill it). Sprint 34 & 35 were far more stable for me.

I'm also experiencing the lag and freezing. Using the keyboard to move the cursor up or down the page is a bit laggy with or without "highlight active" enabled, but it's considerably worse in the latter.

Profiling reveals that it is spending significantly more time in each "operation" function callstack when highlighting is enabled (the codemirror operation function commented "Wraps a function in an operation. Returns the wrapped function." Possibly a codemirror performance issue then?).

ArchBang
Brackets 0.36.0-0

Thanks for the great work.

Scratch the above. I violated the sacred rule of development and didn't test the app in safe mode. I had forgotten that I had the smooth scroll and code map plugins installed. Removing these restores performance.

@david0178418 - ah, good to hear. Thanks for checking that!

@jnewc - would you mind filing a separate bug on the stability issues you're seeing? Please note whether you're seeing the crashes on Mac or Linux (or both). Thanks.

No freezes on Mac. Mint's on my work machine so I'll get back next week if I have the opportunity.

Is their a preferred process for profiling Brackets?
