Mutter offers SPA_META_Cursor with a FIXED size pod — SPA_POD_Int(CURSOR_META_SIZE(384, 384)) in meta-screen-cast-stream-src.c — while our request capped the range at meta_size(256, 256). The intersection is empty, so the Meta param silently failed to negotiate and no buffer ever carried the meta region: the entire Linux cursor pipeline (forward AND blend) was blind on GNOME, proven by an on-glass probe counting 32k+ buffers with zero metas. KWin's offer fits inside 256², which is why the same consumer code passed there. Raise the max to 1024² headroom (the negotiated allocation follows the producer's value, not our max) and align the bitmap parse guard. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
