Bug 512792

STEPS TO REPRODUCE

    Boot into a Wayland session using the integrated AMD Radeon 680M GPU.

    Open and use graphic-intensive or browser-based applications (e.g., Firefox, VS Code).

    Wait for random time intervals (e.g., every few minutes).

OBSERVED RESULT

    The display freezes completely for approximately 1-2 seconds. This issue affects both the built-in and external monitors simultaneously.

    The freezing is much more frequent when using browser-based applications like VS Code and Firefox.

    If typing during the freeze, a massive repetition of the last pressed key occurs immediately after the display unfreezes.

    VS Code exhibits noticeable screen tearing when using the AMD iGPU (this issue disappears when switching to the NVIDIA dedicated GPU).

    The following recurring critical errors appear in journalctl -r immediately preceding or during a freeze event:

Nov 30 21:09:15 RedmiG kwin_wayland[1578]: Failed to create framebuffer: 无效的参数 
Nov 30 21:09:15 RedmiG kwin_wayland[1578]: Failed to create framebuffer: 无效的参数 
Nov 30 21:09:15 RedmiG kwin_wayland[1578]: Invalid framebuffer status:  "GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT"
Nov 30 21:09:15 RedmiG kwin_wayland[1578]: 0x502: GL_INVALID_OPERATION error generated. <image> and <target> are incompatible
Nov 30 21:09:15 RedmiG kwin_wayland[1578]: Invalid framebuffer status:  "GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT"
Nov 30 21:09:15 RedmiG kwin_wayland[1578]: 0x500: GL_INVALID_ENUM error generated. Invalid <face>.

    The kwin_wayland: Wait failed message is also logged, which appears to be closely related to the freezing event:

    Nov 30 21:09:07 RedmiG kwin_wayland[1578]: Wait failed

    A key repeat log is also observed when typing during a freeze:

    Nov 29 15:20:06 RedmiG kwin_wayland_wrapper[1994]: Key repeat discarded, Wayland compositor doesn't seem to be processing events fast enough!

EXPECTED RESULT

The display should render smoothly without random 1-2 second freezes, GL framebuffer errors, or compositor wait failures.

Other notes:

1. This bug is very similar to https://bugs.kde.org/show_bug.cgi?id=511852, but I experienced a severe user experience issue with it.

2. English is not my native language, so some parts may be unclear.

3. I am happy to provide more diagnostic information.
