"Java" crash log from the last time this occurred in Prism Launcher.

SUMMARY

When I utilize https://github.com/flathub/org.prismlauncher.PrismLauncher/tree/275738db15e11445f30262f694951e4603ff623f (the commit returned by `flatpak info org.prismlauncher.PrismLauncher`) after approximately 20 minutes of operation, my display shall freeze, then every 5 seconds disable for 2 seconds and re-appear with corrupted content. This can solely *sometimes* be saved by switching to a TTY and killing my user.

Although https://bugzilla.opensuse.org/show_bug.cgi?id=1220043#c0 describes how previously the system immediately ceased to output audio and respond to all commands (including `SysReq`s to the kernel) this wasn't true today (the last time that I verified that it remained reproducible).

That URI also demonstrates that this first occurred on openSUSE Tumbleweed after a system update, and that I expected it to be OS-specific. However, it's remained since I installed Fedora 40 as its replacement. This leads me to believe that it's upstream somewhere, but I have little idea where. After a *lot* of deliberation, I've considered here the most likely place, considering that KWin under Wayland acts as both compositor *and* display server, and because it's the primary commonality between the OSes I've used thus far.

STEPS TO REPRODUCE

1.  Install https://download.fedoraproject.org/pub/fedora/linux/releases/40/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-40-1.14.iso

1.  *   Prism Launcher (Minecraft):

        ```sh
        flatpak install 'https://dl.flathub.org/repo/appstream/org.prismlauncher.PrismLauncher.flatpakref' && \
        flatpak update 'app/org.prismlauncher.PrismLauncher/x86_64/stable' --commit=0319f34827814955c05d8961e4f1fe50956112afdd86251cc27e416859f97434 && \
        flatpak run -vvv 'app/org.prismlauncher.PrismLauncher/x86_64/stable'
        ```

        Prism Launcher always causes it eventually. Usually within 30 minutes of play time, sometimes 5 or 10.

    *   War Thunder:
    
        ```sh
        flatpak install 'https://dl.flathub.org/repo/appstream/com.valvesoftware.Steam.flatpakref' && \
        flatpak update 'app/com.valvesoftware.Steam/x86_64/stable' --commit=173cd565d98d4951bd858bad290e8481a9e72dbf5f7c9c980165a060666184b1 && \
        flatpak run com.valvesoftware.Steam 'steam://install/236390' && \
        flatpak run com.valvesoftware.Steam 'steam://rungameid/236390'
        ```

        Note that it appears to very, very rarely occur in WT anymore.

OBSERVED RESULT

As https://imgur.com/a/https-discussion-fedoraproject-org-t-random-indefinite-system-hang-110020-8-b6Cpbg1 demonstrates, after approximately 20 minutes of Prism Launcher running:

1.  My display freezes.

    Simultaneously:

    2.  Keyboard (and mouse - all HID) input disables.
    3.  The content is artifacted.

4.  That used to be where it would then automatically reboot. However, recently, it's changed:

    1.  The display renders entirely `#000000`, for a moment.
    2.  Then, usually:

        1.  The content reappears, more artefacted. This shall continue unless I try to do something with the keyboard, like the undermentioned.
        2.  Keyboard inputs (at least, switching to the TTY) finally go through.

        However, today, I was finally able to acquire some logs due to being instead dumped into a crash dump in TTY1, instead of having the display corrupt. What appear to be the traces I saw are undermentioned - I hope they're relevant:

EXPECTED RESULT

None of this should occur, evidently. At the least, if kwin_wayland has a fault, it should crash cleanly, rather than bring down my system with it, especially in the corrupt way that it has thus far.

ADDITIONAL INFORMATION

I have considered whether this is a symptom of a dying GPU. However, it never occurs in anything except WT and Prism Launcher, *seemingly* irrespective of how taxing it is on GPU. However, I don't play much else, so this is mostly anecdotal.

Considering I can usually immediately switch to TTY4, where all is fine, and then switch to TTY1 where it's becoming worse, I can quite confidently assume it's a software fault.

I've really tried my best to make this actionable.

(In reply to Roke Julian Lockhart Beedell from comment #0)
I just installed Windows 11 and played Prism. It didn't crash for the 6 hours I played. This is undoubtedly a software regression in the graphical stacks utilized by Fedora and OSTW (of course, with the commonality of KDE Plasma 5 and 6 accounting for most of that stack, being the DE).
Comment 4 Zamundaaa 2024-06-24 15:31:10 UTC 
This isn't really kwin crashing itself, the crash is in kernel code. Please report this to https://gitlab.freedesktop.org/drm/amd/-/issues
If you can test older kernels, it might help narrow the problem down for amdgpu developers if you find out in which kernel version the issue started to happen.

Thank you, lots. I've done the best I can - https://gitlab.freedesktop.org/drm/amd/-/issues/3462.
