Wasn't quite expecting that. Hmm. Now that I think about it IIRC there was some problem with CRCs when all planes are turned off. I think the spec even says the dmux crc source shouldn't be used with all planes turned off, but I seem to recall the problem only manifesting for a single frame when transitioning between no-planes vs. some planes. However I don't think kms_cursor_edge_walk should even be turning off all the planes. This would seem to need a deeper investigation. -- = Ville Syrj=E4l=E4 Intel _______________________________________________ igt-dev mailing list igt-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/igt-dev
