The solution in #24732 is rather straightforward, but it lead me to check the code for potential other locations. \r\n\r\n### Proposed fix\r\n\r\nThese are the locations I potentially found. It should probably be confirmed that it is a problem before modifying them (and those cases will be a good base for a test):\r\n\r\nhttps://github.com/matplotlib/matplotlib/blob/cc85fb66da61f85259d7d99f06faa6285f4ed225/lib/matplotlib/collections.py#L548-L550\r\n(Here one should probably take a complete look at the `set_offsets`/`get_offsets` setup and see if one can remove redundant calls. See a bit of the discussions in #24732)\r\n\r\nhttps://github.com/matplotlib/matplotlib/blob/cc85fb66da61f85259d7d99f06faa6285f4ed225/lib/matplotlib/collections.py#L2099\r\n(Not sure if it makes sense here.)\r\n\r\nA bunch in quiver, but not sure how well that supports units and masks. Similar with projections.\r\n\r\nAs discussed in https://github.com/matplotlib/matplotlib/pull/24732#issuecomment-1352981155 it seems like `date2num` does not support masked arrays, so making it do that is also a step in the right direction for this.
