What the, this link also crashes KDE Plasma, when opening this link with Google Chrome. I had to reboot two times, just clicking this frame link.

Both times, first journalctl entry in the crash time is:

[drm:__nv_drm_gem_nvkms_map [nvidia_drm]] ERROR [nvidia-drm] [GPU ID 0x00000100] Failed to map NvKmsKapiMemory 0x0000000070a84e8b

Then KWIN dump etc.

Reminding me to buy AMD next.

This is due to a video that has drm encoding and the browser trying to decode it. The drm blob contains the codec keys in our driver and the browser is supposed to negotiate this. It fails. At least on Nvidia for you. It fails for me on safari on iOS.

DRM in context of that log message is Direct Rendering Manager which is a Linux subsystem for handling GPUs; it's unrelated to Digital Rights/Restrictions Management and there are no DRM-encumbered videos on that page.
