http://bugzilla.opensuse.org/show_bug.cgi?id=1204910 Bug ID: 1204910 Summary: Plasma/kwin crashes when switching virtual desktops. Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: rayrock@pm.me QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I am encountering a highly annoying bug with KDE virtual desktops. I believe it may be somewhat related to this: https://bugzilla.opensuse.org/show_bug.cgi?id=1101560 https://bugs.kde.org/show_bug.cgi?id=388127 Hardware: Dell XPS 15 7590, i7 9750h Using INTEL MESA UHD graphics, nvidia 1650 gpu present but unused 4k display 64gib memory 1TiB SSD Description: When transitioning between virtual desktops, kde plasma/kwin becomes 'stuck' sometimes - randomly. Constantly, the plasma desktop docks disappear, windows lose borders/decorations and are unresponsive. Sometimes, keyboard shortcuts still work and I'm able to get into konsole. However, I'm unable to fix the issue without entirely logging out of my graphical session. Other times, hitting the power button will allow me to access logout dialogue. And rarely, I must do a hard reset. I've been unable to find any hint of logs whenever the bug occurs, making it difficult to trace. The issue has been ongoing since I first switched to Tumbleweed in August. Issue has persisted through a fresh install. Issue persists despite having no nvidia drivers installed. (nvidia drivers eat ~4w more at idle, I can't seem to make them not do that despite trying, and I don't really need them anyway so I just don't bother with it). Output of `sudo lshw -c video` ``` sudo lshw -c video *-display UNCLAIMED description: 3D controller product: TU117M [GeForce GTX 1650 Mobile / Max-Q] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: memory:ec000000-ecffffff memory:c0000000-cfffffff memory:d0000000-d1ffffff ioport:3000(size=128) memory:ed000000-ed07ffff *-display description: VGA compatible controller product: CoffeeLake-H GT2 [UHD Graphics 630] vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 logical name: /dev/fb0 version: 00 width: 64 bits clock: 33MHz capabilities: pciexpress msi pm vga_controller bus_master cap_list rom fb configuration: depth=32 driver=i915 latency=0 resolution=3840,2160 resources: irq:147 memory:eb000000-ebffffff memory:80000000-8fffffff ioport:4000(size=64) memory:c0000-dffff ``` output of `inxi -G`: ``` Graphics: Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] driver: i915 v: kernel Device-2: NVIDIA TU117M [GeForce GTX 1650 Mobile / Max-Q] driver: N/A Device-3: Microdia Integrated_Webcam_HD type: USB driver: uvcvideo Display: x11 server: X.Org v: 21.1.4 with: Xwayland v: 22.1.4 driver: X: loaded: modesetting unloaded: fbdev,vesa gpu: i915 resolution: 1920x1080~60Hz OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 22.2.2 ``` I have not encountered the bug on Wayland, but I also still have issues with wayland crashing on login with this machine which I simply don't want to investigate since x11 sill works. I also have issues with blurry apps in wayland, so it is a no-go. I am led to believe it is similar to #1101560, because at this time, disabling `System Settings > Workspace Behavior > Virtual Desktops > Show on-screen display when switching` has fixed the issue. With the OSD disabled on switching, I no longer encounter the bug. Additional points to reinforce: This bug was present when I had nvidia drivers installed, and has persisted on a very bare fresh install with no nvidia drivers. I would be happy to do some more digging, if necessary. -- You are receiving this mail because: You are on the CC list for the bug.
