how to fix? ;/

[vladisslav2011]

Hello. Provide a backtrace, please.

1. Run gqrx under gdb

$ gdb gqrx
(gdb) run

2. Make it crash
3. Switch to a terminal with gdb and type bt
4. Post backtrace here

I don't think running gqrx under root to be a good idea...

Hi, same issue on manjaro.

@Inglebard It looks, like there is a problem with either qt6ct theme plugin or missing font. Have you tested other Qt6 applications with qt6ct platform theme?

[Inglebard]

@vladisslav2011 you are right. I clear my /etc/environment where some QT variable were set. Now it starts properly, thanks.

I'll close this off, since the problem appears to lie outside Gqrx.
