I haven't seen this problem with Plasma 5.27.6 in Fedora Rawhide VMs using Fedora-KDE-Live-x86_64-Rawhide-20230805.n.0.iso with nomodeset on the kernel command line and the simpledrm 5.5-rc4 kernel driver, llvmpipe from Mesa 23.1.5, KF 5.108.0, Qt 5.15.10. So the problem might been fixed already. 5.27.7 hasn't been built completely for Fedora yet. I'll comment if I see the problem again with 5.27.7 after it's built for Fedora. I read the instructions for building Plasma a while ago, but I haven't tried building it before. Thanks. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=466633 --- Comment #3 from Matt Fagnani --- Created attachment 156974 --> https://bugs.kde.org/attachment.cgi?id=156974&action=edit drm_info output from in the VM I booted the Fedora 38 live image Fedora-KDE-Live-x86_64-38-20230302.n.0.iso in a QEMU/KVM VM using GNOME Boxes in basic graphics mode in grub with nomodeset on the kernel command line. The llvmpipe mesa 23.0.0-rc4 and simpledrm drivers from the 6.2.0 kernel were in use. Plasma 5.27.1 on Wayland started. I started Konsole and installed drm_info with sudo dnf install drm_info. The black bars appeared at the top of the screen while installing drm_info. I'm attaching the drm_info output. The black lines/bars showed up at two other times when using the VM.
