--- Comment #4 from Víctor M. Jáquez L. <vjaquez at igalia.com> ---
IIUC you're reporting two different problems

1. A lot of drops when using gl sink. Perhaps something (decoding, upload, color conversion, etc.) is slugging the rendering.
2. the dma's drm format is not negotiated so the image is not well rendered using the dmabuf sink. For this issue we need to finish https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3524

For both cases, perhaps adding a vapostproc after the decoder as video filter might help.
