Hey 👋

I'm trying to reproduce this on Intellij 2024.2 but I'm not actually getting any suggestions when I try to rename a field. Are you using the built-in AI Assistant by any chance to power these suggestions?

Or is this somehow exclusive to Rider?

[mnemotic]

I think this could be specific to Rider / ReSharper plugin, but I'm not 100% positive on that. Definitely not AI Assistant. I have that disabled.

[sgoudham]

Can you provide the file that you were working on? I'd like to try and invoke the rename dialog on specifically the field shown in the screenshots

[mnemotic]

I don't see how that's relevant but I've attached a different file that has the same issue anyways.

Program.zip

I trigger the Rename dialog either by pressing F2 or through Refactor / Rename... menu item. Any member of a class or struct will get a Rename dialog; local variables get a suggestion list "in-line", without a Rename dialog and that list does have a highlight. You can try to rename index local variable and FindIndexOfFirstNonEmptyBin method in the attached code to see the difference. The latter should get a Rename dialog.

HTH

Is there anything I can do to contribute to troubleshooting this issue?

[sgoudham]

Hey, sorry I haven't had a chance to look at this.

I definitely can't reproduce this on Intellij as shown below so I'd have to guess it's a Rider specific thing

[mnemotic]

I also failed to reproduce this in IntelliJ. I think you're right about this being Rider-specific.

[sgoudham]

Not sure why I didn't think of this earlier, are you able to reproduce this behaviour on the default Dark colour scheme or any other colour schemes that offer both dark/light variants? That would let us know if it's a Rider specific problem caused by Catppuccin or if it's a bug with the underlying system.

[mnemotic]

Good thinking! I just tested this and all built-in and bundled dark themes, including Dark, have the selection highlight. I also tested two custom dark themes: One Dark and Gradianto. Both of these also have the selection highlight.

[sgoudham]

Well that doesn't make me too happy 😅

I'm honestly not really sure where to go from here, I know in the last year or two, JetBrains actually automatically control the contrast for some of the popups so we had to make some weird changes - not sure if those are coming into play here 🤔

I guess the next step is to try and find the key that's controlling the contrast and see if we can change it to see what happens / what other popups it affects.

[mnemotic]

Sorry to be the bearer of bad news. 😅

Is there anything I can do to assist?

[sgoudham]

I would like to check if this key is the reason why it's not showing up properly:

jetbrains/generateFlavours/ui.theme.json

Line 134 in 270eaff

"selectionBackground": "surface1",

i.e. if you changed it to something like surface2, recompiled the theme and installed it into your Rider IDE - does it look any different?

[mnemotic]

Changing selectionBackground from surface1 to surface2 changed the highlight color of the selected line for the "inline" rename suggestion list for local variables from #494D64 to #5B6078, making it appear brighter. It did not affect the highlight in Rename dialog in any way. 🙁

surface1 (#494D64)

surface2 (#5B6078)

[sgoudham]

I suppose it means that isn't the relevant key, if you install the Plugin Devkit plugin, you should get code completion for the ui.theme.json file and maybe there's a key in there that specifies the Rename dialog?

[mnemotic]

I'll try installing the plugin devkit this upcoming weekend and see if I can find which key this is.
