Description Reece 2016-02-29 12:56:03 UTC

The GTK+ Widget Style that comes with Kubuntu has graphical issues that have effected every theme I have tried it with (it borrows elements from the activated GTK theme. I have tried this with "Arc" (a lighter theme) and "Numix" (a darker theme).

In Dolphin when you click to select a folder (with double click enabled in mouse input settings) the highlight is bright white. This makes it unable to view the name of the folder until you move the mouse away.

This is a problem to those who want a unified look between QT and GTK apps.
Thank you for your time and as this is my first bug filed, please forgive any categorisation mistakes I have made, I did look but couldn't find any more fitting ones.

Reproducible: Always

Steps to Reproduce:
1. Open "System Settings"
2. Enter "Input Devices" and select "Mouse"
3. Enable "Double Click to open files and folders"
4. Go back to main Settings page and select "Application Style"
5. Choose "GTK+ Style" as the "Widget Style"
6. Open Dolphin and click on a folder once
7. Move your mouse over the highlighted folder

Actual Results:  
The highlight turns white which makes the text unreadable.

Expected Results:  
The name of the folder should highlight in a colour related to the theme.

I am running Kubuntu 15.10 with the Kubuntu Backports PPA added for Plasma 5.5.4

This also affects the Dolphin sidebar.

Hi Reece
First, thanks for reporting the problem and posting the bug report !
Now, unfortunately, it is in fact a Qt bug, and cannot be fixed by us. 
gtk+ is a widget style that is maintained by Qt (not by KDE, nor Breeze, meaning: not us), to "copy" the gtk theme settings into a Qt style, and apply it to Qt applications. 
Bottom line: bug should be reported there.

As for integration, possibly you do not need to use the gtk+ theme. 
You could use the "native" oxygen qt theme, and the oxygen-gtk themes that go with them (but they are unfortunately unmaintained as we speek)

Or the native Breeze Qt theme, and their (maintained !) gtk counterparts. 
That should give you enough (if not perfect) consistency.

Best regards,

Hugo

Thank you for the nice response and for pointing me in the right direction! I've headed there and reported the bug to QT.
