Because most of the applications have a white background, I use the OSX's invert colors options so to reduce eye strain with prolonged use.

Always when switching between normal and inverted colors, svnX crashes with the following backtrace:

To Invert colors, go to System Preferences > Keyboard > Shortcuts > Accessibility > Invert Colors, and assign a shortcut.

I was wondering if you guys knew about it, and if anyone else can reproduce it.

Thanks!

Unfortunately your stack trace showed no (svnX) application code, only OS code.

That makes it difficult to pin down in svnX.

I have never observed this problem and I have been unable to reproduce it.

I tried 2 OSes, release & debug builds of svnX, various additional Accessibility changes, changing svnX’s Prefs > Working Copies colour settings, changing a Working Copy window display mode and even adding multi-coloured emojis to file names 😅.

Which window was active in svnX? Which display options? Does it crash if you launch svnX after Invert Colors? Does it crash if it is not the front app?

Does the crash happen if you launch svnX and then hit the Invert Colors key combo (⌃⌥⌘8) without doing anything else? Have you changed the key combo?

Exactly which versions of svnX & macOS are you using?

Are you using any other Accessibility settings or svnX settings that may be relevant?

Please send me a (zipped) copy of the full crash log. You should find it in ~/Library/Logs/DiagnosticReports/svnX….crash.

Regards,

CHRIS

Hello chris,

When I posted this problem, I couldn't see the post, so I thought that it didn't work, and completely forgot about it. Sorry for leaving it like this.

In the meantime, after several updates OS and maybe snvx, it does not reproduce anymore, so yeah, it could have been a problem from the system.
