SUMMARY KDE crashes the virtual machine while using VirGL acceleration on KVM/QEMU everytime when the opening system monitor, dragging and dropping Disk Usage widget or expanding Network Manager widget. STEPS TO REPRODUCE 1. Install (or run LiveCD) Fedora KDE / Kinoite or OpenSUSE Tumbleweed on Virt-Manager with VirtIO graphics and OpenGL enabled 2. Launch the VM 3. Open System Monitor or expand network details in the Networks widget from system tray OBSERVED RESULT VM crashes EXPECTED RESULT Operating system should still continue to run and Plasma should not crash SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora KDE 37, OpenSUSE Tumbleweed (available in About System) KDE Plasma Version: 5.25.5, 5.26 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION This does not happen on KDE Neon user edition. If OpenGL acceleration is turned off, this issue does not happen but graphics becomes slow.
Additional info: Happens on both X11 and Wayland.
So we have one program using OpenGL supposedly crashing another program using OpenGL? That sounds much more like a graphics driver bug than something Plasma does
I agree that Plasma itself is not responsible for the crash. But wondering if something changed on Qt which is causing it.
As you said it's more likely from graphics drivers. I created a bug report under Mesa. https://gitlab.freedesktop.org/mesa/mesa/-/issues/7520
