Comment:
The issue is Sway decides to use the new compressed plane modifiers which
Intel uses for power savings, however, kmsgrab doesn't yet support
capturing those, but even if it did, you wouldn't be able to do anything
with them since neither Vulkan, nor VAAPI, nor OpenCL supports such
surfaces yet. Vulkan seems to be the closest to supporting those, all we
need is for Mesa to implement support for that. VAAPI doesn't seem to have
a patch to support those yet.
You can patch your sway to avoid using those modifiers for some
unnoticeable lossless in power savings.
So, its not our bug for the moment. Once some API supports importing such
DMABUFs we can change kmsgrab.
