Hi everyone,
I recently installed Fedora with KDE and really liked the experience. In my daily workflow, I use Distrobox with Ubuntu inside Fedora to run OpenFOAM, since the official precompiled packages are provided for Ubuntu (and I rely on ParaView through paraFoam for my PhD research).
However, I’ve noticed that some GUI applications inside the container — like ParaView — are annoyingly laggy when running on KDE. Interestingly, this doesn’t happen when using Fedora with GNOME. In that case, everything inside Distrobox works flawlessly.
I’ve tested this thoroughly, reinstalling the system twice with each desktop environment. The difference in performance is very consistent: KDE seems to cause this graphical lag inside the container, while GNOME doesn’t.
Has anyone faced a similar issue or knows what might be causing this? Is there any KDE-specific setting I could tweak to fix this behavior? I’d love to stick with KDE, but this issue is pushing me back to GNOME.
