Ah, so you want to disable tiling for staging and stream usage cases, not blitting. That makes sense. However blitting between non-tiled textures in our transfer path is completely valid and recommended if the transfer is write-only and mapping would require synchronization (flush + bo_wait). In such a case, the blit will almost always be faster regardless of whether tiling is enabled or not.
