--- Comment #28 from Zamundaaa <xaver.h...@gmail.com> --- Git commit b14f7959eb5f4d2b690ac26fdfee76abc837240c by Xaver Hugl. Committed on 12/04/2023 at 13:28. Pushed by zamundaaa into branch 'master'. backends/drm: add another multi gpu fallback With the dmabuf multi-gpu path, a buffer is imported to the secondary GPU and presented directly, but importing a buffer that's usable for scanout is not possible that way on most hardware. To prevent CPU copy from being needed in those cases, this commit introduces a fallback where the buffer is imported for rendering only, and then copied to a local buffer that's presented on the screen.
