Expected Behavior

When I open a diff window, I want to see the diff window highlighting, even when the cursor is inside of a scope.
In this image the cursor is on line 2, outside of the scope.

Current Behavior

The scope highlighting overrides the diff highlighting.
In this image the cursor is on line 4, inside the scope.

Code snippet for reproduce

Any piece of code that has scopes. Example from the images:

package com.example

data class SomeOtherFile(
    val id: String,
    val description: String,
)

Hi @Aaron-Engler! I'm Dosu and I’m helping the intellij-rainbow-brackets team.

This appears to be a new issue. I didn't find any existing reports specifically about scope highlighting overriding diff window highlighting.

However, a very similar conflict was reported in Issue #2883 for debugging sessions, where scope highlighting interfered with the debugger's execution point highlighting. In response, the maintainer added a "suppress scope highlighting when debugging" option in version 2025.3.7+.

Workaround for now: You could try reducing scopeHighlightStrength to 0 in your settings to effectively disable scope highlighting:

<option name="scopeHighlightStrength" value="0" />

This would prevent the conflict but would disable scope highlighting globally, not just in diff views.

Given that a similar context-specific option was added for debugging, it may be reasonable to request a "suppress scope highlighting in diff/VCS windows" option modeled after that feature.

To reply, just mention @dosu.

@dosu Updated to the latest version (2025.3.8) and enabled the 'suppress scope highlighting when debugging' option, but the issue is still there. This did not fix it.

[dosubot]

That's expected — the "suppress scope highlighting when debugging" option only applies to debug sessions, not diff/VCS windows. Your issue is a separate case that doesn't have a dedicated toggle yet.

As a workaround, you can try setting scopeHighlightStrength to 0 in your settings to completely disable scope highlighting:

<option name="scopeHighlightStrength" value="0" />

This would prevent the conflict globally, but you'd lose scope highlighting everywhere, not just in diff views.

Since the maintainer recently added context-specific suppression for debugging in Issue #2883, your issue here could serve as a feature request for a similar "suppress scope highlighting in diff/VCS windows" option.

To reply, just mention @dosu yıld?

Thanks for the quick reply and fix. I just installed the snapshot, enabled the new option and my diffs now work properly.
Thank you!
