In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Disable AFBC support on Mediatek DRM driver
Commit c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek DRM driver") added AFBC support to Mediatek DRM and enabled the 32x8/split/sparse modifier.
However, this is currently broken on Mediatek MT8188 (Genio 700 EVK platform); tested using upstream Kernel and Mesa (v25.2.1), AFBC is used by default since Mesa v25.0.
Kernel trace reports vblank timeouts constantly, and the render is garbled:

Until this gets fixed upstream, disable AFBC support on this platform, as it's currently broken with upstream Mesa.
