[Help] Qt Apps Like Brave Browser and Cisco Packet Tracer Are Unusable — Can't Click Anything

English Applications

Hey everyone,

I’m running into a frustrating issue with some Qt-based apps on my Linux setup (openSUSE Slowroll in my case, but this might affect Tumbleweed). Applications like Brave Browser and Cisco Packet Tracer launch fine and aren’t frozen — animations work. — but I can’t click on anything inside the window. No buttons, menus, or even tabs respond to clicks.

I don’t use either of those two apps…are you using Plasma Wayland?

The results from inxi -Gaz might be useful here.

If you create a new user, and login to the desktop as that new user, does the same issue present itself?

BTW, Brave is not a Qt application.

Brave works fine on my Tumbleweed.

Now are for updating Slowroll?

Thanks for clarifying that Brave isn’t Qt

@farhatizakaria which version 8.2.2 (QT5) or the beta 9.0.0 (QT6)? If it’s the beta version then in the /opt/pt/bin directory add a softlink ln -s /usr/lib64/libtiff.so.6 libtiff.so.5

Yes, I usually use 8.2.2 for Packet Tracer, It was working smoothly back then. Do I miss something ? should I change the desktop environment ?

@farhatizakaria well no issues with the 8.2.2 version here… perhaps try the beta version and see?
