Arch Linux User Repository

Since python has recently been upgraded to 3.13, you need to rebuild the package if you installed it last before the upgrade, e.g., with yay (thanks @marco.righi) you can:

yay -S zapzap --rebuildtree  --noconfirm  --rebuild --sudoloop

This PKGBUILD uses a pacman feature to compute checksums in CVS packages, which requires pacman>=6.1.0. If you're coming from Manjaro or an other Arch-based distro with pacman<6.1.0, you need to pass --skipchecksums to makepkg, if building manually, or, if installing with yay, add --mflags --skipchecksums, e.g.:

yay -S --mflags --skipchecksums zapzap

There was a problem when running after a full system update.

ImportError: libtheoraenc.so.1: cannot open shared object file: No such file or directory

The flatpak version is working, but for some reason aur isn't.

edit: I tested another package and it was giving me a similar problem related to libtheoraenc.so.1.

In this case I fixed it (at least temporarily) by making a symbolic link to the same lib with a different name

sudo ln -s /usr/lib/libtheoraenc.so.2 /usr/lib/libtheoraenc.so.1
sudo ln -s /usr/lib/libtheoradec.so.2 /usr/lib/libtheoradec.so.1

Setting "QMLSCENE_DEVICE=softwarecontext" or "MESA_LOADER_DRIVER_OVERRIDE=zink" is a workaround for this issue.

Jep that's the first thing that I tried, and unfortunately the window is still glitching. I also tried disabling the hardware acceleration in the settings, which didn't change anything, and tried to disable Wayland, which notably changed the way the glitches look but nothing else ^^

Have you tried from terminal:

QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu --disable-gpu-compositing" zapzap

Just to make sure it doesn't work. Since I don't see overriding this env variable anywhere in zapzap code.

Unfortunately, the workaround proposed in the forum is not working with ZapZap, even if you set the environment variable (QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu --disable-gpu-compositing") globally for the login shell.
Any idea how this could be passed correctly to ZapZap?

Seems to be a current issue with Qt WebEngine: https://bugreports.qt.io/browse/QTBUG-135786
Also reported in the KDE forums: https://discuss.kde.org/t/some-of-my-kde-apps-arent-working-properly/32522/11

Let's hope this gets fixed quickly.

Looking at the GitHub issue report, and your system info, looks like you're both using AMD GPUs. So maybe this issue is Radeon-specific. I've no experience with them, perhaps there's something useful at https://wiki.archlinux.org/title/AMDGPU page, but I don't see anything obvious.

Here is my system info:

Operating System: Manjaro Linux KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.12.0 Qt Version: 6.9.0 Kernel Version: 6.12.22-1-MANJARO (64-bit) Graphics Platform: Wayland Processors: 6 × Intel® Core™ i5-8600K CPU @ 3.60GHz Memory: 31.2 GiB of RAM Graphics Processor 1: AMD Radeon RX 6800 Graphics Processor 2: Intel® UHD Graphics 630 Manufacturer: Micro-Star International Co., Ltd. Product Name: MS-7B46 System Version: 1.0

As you can see, I am on Manjaro Linux, but it's the unstable branch, so the package versions should be mostly the same as Arch. Also, the user on Github reported that he is using Arch, so I don't think it's Manjaro-specific. I am using the open source AMD drivers (Mesa/ Vulkan-Radeon)

@MajorMayer

Interesting, I also run latest KDE Plasma on Wayland: System Info

And zapzap works fine. Maybe it's the latest Nvidia drivers that I use? What GPU(s) do you have?

As mentioned in the upstream repository, this package has issue on the latest KDE Plasma (Wayland): https://github.com/rafatosta/zapzap/issues/354 I can't find any error messages in the logs, but the windows is that broken, that you cannot use the app anymore.
