QCheckBox and QRadioButton not displaying boxes or marks

[swurl]

Whenever I open any Qt 6 application (whether written by me or not), checkboxes and radio buttons are rendering the text totally fine but don't show the checkbox/circle. Clicking the box/circle does change the state of the checkbox but it doesn't show it graphically. Here's an example in qt6ct:

FWIW, here's my system info:

OS: Artix Linux x86_64 
Host: VivoBook_ASUSLaptop X512DA_X512DA 1.0 
Kernel: 6.2.13-artix1-1 
Uptime: 6 hours, 25 mins 
Packages: 1698 (pacman) 
Shell: zsh 5.9 
Resolution: 1920x1080 
WM: sway 
Theme: Artix-dark [GTK3] 
Icons: breeze-dark [GTK3] 
Terminal: kitty 
CPU: AMD Ryzen 7 3700U with Radeon Vega Mobile Gfx (8) @ 2.300GHz 
GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series 
Memory: 5842MiB / 9894MiB 

note that I am not running a DE, instead, I'm running pure Sway (wayland). This problem occurs both under the xcb and the wayland platforms.

Hi and welcome to devnet,

Which version of Qt 6 is it ?
Can you share a minimal compilable example ? So we can check that.

@SGaist there's more here, but no mention of the exact Qt version, just that he's using qt6ct.

[swurl]

@SGaist Qt 6.5.0. This happens in all Qt 6 applications, whether it be qt6ct or a home-compiled application.

@swurl Does the behaviour change if you execute the program thus: qt6ct -style Fusion or qt6ct -style windows ? This could be an attempt to apply a GTK-like theme to Qt.

@ChrisW67 It did not. I ended up reinstalling Linux and that seems to have fixed it. I still have the old install available so I'd like to find out the root cause still.
