QtCreator dark themes unreadable

abstracted8

This is QtCreator 4.9.1 on Qt 5.12.4
Was installed using the system package manager.

I have tried deleting all configuration files/folders I could find in ~/.config as well as reinstalling QtCreator.

@abstracted8 can you try the official Creator from download.qt.io ? (you can install in your home dir and uninstall later). just to see if that is a generic or distro problem.

Hmm, the official download you suggested works correctly. I may have to just use that, as I am unsure how to correct the disto version.

I suggest you report this to your distro's maintainers. They could know what to do, and fix it for all users of Arch Linux.

While this topic is a few months old, but I hope someone else searching for a solution to this issue might find this reply helpful.

The issue seems to occur because the Qt style plugin is now separated from the qt5-base package in Arch Linux (and its derivatives such as Manjaro etc.) . The details can be found in the Arch wiki page for Qt and GTK style compatibility: https://wiki.archlinux.org/index.php/Uniform_look_for_Qt_and_GTK_applications#QGtkStyle

To fix the issue:

Make sure that the qt5-styleplugins package is installed (sudo pacman -S qt5-styleplugins)
Set the environment variable QT_QPA_PLATFORMTHEME=gtk2 before executing QtCreator (preferably export this from the ~/.bashrc file).

PS: Downloading the official QtCreator might not be possible always, such as when using Arch Linux on a ARM device.

Thanks for the solution. I am having this issue on Arch Linux as well. However, I'm running KDE. Before I follow the above steps, can anyone say how they differ in KDE? Do I still need to set the environment variable QT_QPA_PLATFORMTHEME=gtk2?

Qt Creator is not a GTK app after all...

Hi
the same problem on Fedora 31 KDE. I switched from default to Breeze Dark theme.
I installed QtCreator and all menus were unreadable.

However I changed QtCreator theme from Flat to Dark and I can see menu items now.

Thank you. I'm not sure how I missed that setting. I appreciate your screenshot.

I also found this theme I may try:

@ind3r I had this problem on Fedora 32. Your solution worked perfectly.
