After a fresh install, I tried to run Falkon with no success. It crashes on start. Sometimes it actually starts but when it does, if I click the default bookmark titled Falkon Wiki, it crashes and/or freezes the entire desktop. Falkon froze the entire desktop twice. I couldn't even use a TTY Terminal. Debian Buster (stable) Kernel: 4.19.0-6amd64 KDE Plasma Version: 5.14.5 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.3
Update: On it's first try, it inmediately froze the entire desktop interface when I tried to run it using Netrunner 19.08, which uses Debian Buster repos. I couldn't move the mouse nor the shortcut to bring a TTY Terminal. Also, I used Free Drivers on both occasions.
UPDATE The issues was fixed by installing Nvidia Propietary Drivers. Nouveau and QT5-WebEngine have issues.
Thanks for the update; changing status. Noveau driver being incompatible with QtWebEngines usage of OpenGL from multiple threads is a known issue and some distributions switch to software rendering when detecting this combination to avoid crashes.
Created attachment 122825 [details] attachment-13452-0.html It would be helpful if you could put update the issue regarding Nouveau and QT5-WebEngine on Falkon's website. This will certainly help and save time to not so technical users. I spent hours trying to figure out configurations and then finally read online the issue regarding QT5-WebEngine. I have another question. Smoothscrool using the mouse doesn't work on Debian 10 but it does work on Kubuntu. I checked everything and the only differences are the Kernels and QT Versions. Why can't smoothscrooll and bookmark previews work on Debian? Is this because Kubuntu is using Kernel 5.0 or because Kubuntu is using KDE 5.12 LTS?

Debian uses old software versions, because there is a long testing phase. Improvements made to newer versions are rarely backported, unless they are critical.
