Memory leak in Color Scheme Editor

[cyberbit]

Short Summary

The Color Scheme Editor takes a long time to update the interface in some cases. I discovered that while it is running, memory usage takes a huge leap (see attached image).

Steps to Reproduce

Open Task Manager. Open Color Scheme Editor. Make some changes. Click Apply.

Expected results

Memory/CPU usage spikes slightly, then returns to normal once completed.

Actual results

Memory usage continues to grow, CPU is pegged.

Platform Information

Komodo Edit or IDE? Edit Komodo Version? 10.0.0 Operating System (and version)? Windows 7 x64

Woah that's a lot. I'm not seeing this myself on Linux.

Could you try reproducing this in safe-mode? Help > Troubleshooting > Restart in Safe-mode.

I restarted in Safe Mode, and it wasn't as drastic as before. Perhaps an addon is to blame?

Before making a bunch of changes (changing themes, fonts, colors, back and forth several times):

After:

[cyberbit]

I tried again with my configuration, with all addons disabled. That tiny hump in memory about 30% in was changing a CSS property in the LESS editor. That huge hill was deleting a style block from the LESS. The CPU was pegged for that whole time. I watched the memory usage jump from ~600 M to 1500+ M in less than 5 seconds. The whole Komodo interface froze and the side panes lost their styles, like you would see if CSS fails to load on a webpage. Unfortunately I didn't get a screenshot of that in time. As I'm writing this, it's been about 10 minutes and it's settled down to about 800 M.

Ok so interacting with the dialog is crucial to reproducing your issue? What type of changes are you making? Does applying them factor into it or does the "leak" happen without applying?

Ok so interacting with the dialog is crucial to reproducing your issue?

Yes, I would say interacting with the dialog is at least correlated to the problem, if not the causation.

What type of changes are you making?

For my config, simple colors and fonts. Sometimes a LESS change, like adding

font-size: 1rem !important;

in a block.

Does applying them factor into it or does the "leak" happen without applying?

Applying definitely factors into it. It will fluctuate without applying, but that could be attributed to Komodo background tasks. As soon as I apply it, there is definitely some change.

[Naatan]

Hmm I can reproduce it simply by repeatedly applying the color scheme to the interface.

I'll dig into this. Hopefully it's not a Mozilla bug, but it looks like it might be.

[Naatan]

For now I'd recommend you restart Komodo after you're done configuring your color scheme.

@Naatan Sounds good to me. Hopefully I'll decide on a scheme I like, haha!

Being me becomes harder and harder each time soneone finds a bug related to color schemes.
