SUMMARY Specifically on Wayland using an Nvidia GPU Krunner will not show, after toggling it a few times (it will show a maximum of 3 times). The issue does not occur on 2 other machines using Intel IGP's. The issue does not occur on X11. I can confirm the issue also occurred on 5.25.0 but have not tested older versions as Nvidia + wayland was not really usable before 5.25 for me at least. I saw someone comment my exact issue on this bug: https://bugs.kde.org/show_bug.cgi?id=454671 But the bug itself describes a different issue. STEPS TO REPRODUCE 1. open Krunner with a keyboard shortcut (ALT+Space in my case) 2. close Krunner either by clicking on something else or by using ALT+Space 3. open Krunner again 4. close Krunner 5. open Krunner 6. close Krunner 7. open Krunner (krunner will no longer show) Aditional info: running kKunner from command line, I get the following: When launching: qt.qpa.wayland: Wayland does not support QWindow::requestActivate() The second time opening after closing: QCommandLineParser: argument list cannot be empty, it should contain at least the executable name kf.plasma.quick: Couldn't create KWindowShadow for View(0x7ffee8a255d0) kf.plasma.quick: Couldn't create KWindowShadow for View(0x7ffee8a255d0) kf.plasma.quick: Couldn't create KWindowShadow for View(0x7ffee8a255d0) kf.plasma.quick: Couldn't create KWindowShadow for View(0x7ffee8a255d0) qt.qpa.wayland: Wayland does not support QWindow::requestActivate() Third time, the same as the second (krunner still shows) Fourth time, same as the second, only krunner no longer shows After that only: QCommandLineParser: argument list cannot be empty, it should contain at least the executable name SOFTWARE/OS VERSIONS KDE Plasma Version: 5.25.1 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.5 HARDWARE GPU: GTX 1080 Number of displays in use: 4
To add to this, not just krunner but a lot of other stuff glitched out(like opening panels, and simple applications as Steam outright freeze and no longer open after they were opened). Just for info - the issue wasn't present in 5.24.5

More details: - clicking on buttons in the System Tray doesn't always open the desired popup — the frequency of this happening is nod related to high resources' usage; - typing in KRunner hangs — the input is regitered, so if I type "system settings" and press enter, the query isn't displayed, but KRunner correctly opens System Settings OS: openSUSE Tumbleweed 20220628 KDE Plasma: 5.25.1 KDE Frameworks: 5.95.0 Qt: 5.15.2 Kernel: 5.18.6-1-default (64-bit) Graphics Platform: Wayland CPU: AMD Ryzen 5 2600 Six-Core Memory: 7.7 GiB RAM Graphics Processor: NVIDIA GeForce GTX 750

Apologies, forgot to change that I use Arch Linux
Same thing with my PC, but for Application Launcher. I'm using Fedora 36 KDE Plasma Spin.
This bug is in 5.25.90 too. GTX960 Linux fr Scratch source build Qt 5.15.5 NV 515.57 drv.
(In reply to archetech from comment #6) > This bug is in 5.25.90 too. GTX960 Linux fr Scratch source build Qt > 5.15.5 NV 515.57 drv. Can you confirm if it's still present if you set your env variable - QSG_RENDER_LOOP=basic ?
I am using KDE Plasma 5.26 Beta / Wayland and "QSG_RENDER_LOOP=basic" does not solve this problem.

NVIDIA/Wayland/Fedora 37/KDE Plasma 5.26.5 - same trouble
Same stuff on Tumbleweed with Plasma 5.27.3 - also on nvidia GPU.
It's been almost a year and it's still the same. KDE apparently doesn't care about NVIDIA users. Also, the panel freezes from time to time completely visually. This has been the case for a long time. So NVIDIA users will always have a problem with KDE. I recommend using Sway(with Vulkan renderer) or Hyprland.
Actually I'd call this a major showtrooper and it must be fixed before plasma 6.0 (when wayland is the default)
Happening for me too on Manjaro + KDE Wayland + NVIDIA GPU.
Same issue here, it happens very often. I have to kill krunner to be able to use it again. Fedora Linux 38, KDE Plasma Version: 5.27.8, KDE Frameworks Version: 5.110.0, WAYLAND, NVIDIA RTX 3080
Another repro! KDE Plasma 5.27.8 Debian 12 (SID) Wayland Nvidia RTX 4090
Hackey workaround: create a custom shortcut with "add command" in the Shortcuts menu and write `pkill 'krunner'`. Or alternatively, just give up on krunner and launch applications with the app launcher.
Does QSG_RENDER_LOOP=basic krunner --replace fix this issue or at least help?
(In reply to David Redondo from comment #18) > Does > > QSG_RENDER_LOOP=basic krunner --replace > > fix this issue or at least help? It does not, krunner still hangs after spam clicking its hotkey
forcing qml software render also does not help: `QSG_RENDER_LOOP=basic krunner --replace` - krunner hangs `QMLSCENE_DEVICE=softwarecontext krunner --replace` - krunner also hangs `QMLSCENE_DEVICE=softwarecontext QSG_RENDER_LOOP=basic krunner --replace` - krunner hangs
When you say hangs, you mean it doesn't open or is visually frozen? Can you run qdbus org.kde.krunner when "frozen" and confirm if it prints results?
UPDATE ----------- For me the issue has been resolved with one of the plasma or framework updates. Now running the following: Operating System: Fedora Linux 39 KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 Kernel Version: 6.6.4-200.fc39.x86_64 (64-bit) Graphics Platform: Wayland Graphics Processor: NVIDIA GeForce RTX 3080/PCIe/SSE2 and now krunner is working consistently.
it does qdbus org.kde.krunner / /App /MainApplication /org /org/kde /org/kde/krunner the krunner window in frozen state is not shown on screen or in kwin overview
Just for reference, I personally no longer use Nvidia hardware since early this year but other people seem to be more than capable of handling it.
Created attachment 164023 [details] krunner log when it dissapears If I list kwin clients with the script described in https://unix.stackexchange.com/questions/706477/is-there-a-way-to-get-list-of-windows-on-kde-wayland I get KRunner there when it works as expected, but there are no krunner script when it stops showing even though the `krunner` process exists: 8589 chermnyx │ 0.0 0.7 00:00:00 │ /usr/bin/krunner Seems like it stops being able to create window I've tried to run kurnner with `QT_LOGGING_RULES='*=true' krunner` and got the following when it hangs: qt.qpa.wayland.backingstore: Didn't receive frame callback in time, window should now be inexposed

Per Bug 477762 Comment 16, this is an NVIDIA issue that's fixed upstream in Qt via https://codereview.qt-project.org/c/qt/qtwayland/+/503674. We also have an option to work around the issue via https://invent.kde.org/plasma/plasma-integration/-/merge_requests/119 in case that Qt patch isn't merged in time for the Plasma 6 launch.

setting `QT_QUICK_BACKEND=software` works as a workaround
(In reply to Dmitrii Chermnykh from comment #30) > setting `QT_QUICK_BACKEND=software` works as a workaround Is there a way to apply this workaround permanently? Notably there seems to be no krunner.desktop anywhere.
(In reply to Szczepan Hołyszewski from comment #31) > Notably there seems to be no krunner.desktop anywhere. There is /usr/share/kglobalaccel/org.kde.krunner.desktop, but copying it to ~/.local/share/applications and editing there has no effect.

I added the following lines to the ~/ .bashrc file: QT_QUICK_BACKEND=software QSG_RENDER_LOOP=basic But the plasma panel still opens its menu every other time.
