Very Strange Triangulation of Segmentation, Cannot Globally Update Marker Size or Face Color

I tried out napari-spatialdata on a Xenium project and I noticed a few usability issues. I wonder if these are specific to me (maybe my workstation doesn't have sufficient resources? I have an M1 macbook with 16GB memory). Overall the program was very laggy/non-responsive so that makes me suspect a resource limitation.

The first thing is that the triangulation of the segmentation shapes seems kind of wonky. This is not at all what the nuclear segments look like in the Xenium browser. Is there some configuration parameter I can pass to get a higher poly rendering of the segments?

After that there were a few usability issues, like not being able to change the size of the transcript dots globally, however adjusting the opacity globally seemed to work fine.

It seems I need to actually select the dots to change their size, but when I try and use cmd-A to select them all the software crashed (hung indefinitely).

Maybe these issues are not relevant to this software project directly but I'm just curious if something is horribly wrong with my installation or if this is expected. If I'm viewing a full Xenium slide should I maybe downsample to just one quadrant of the image maybe?

Start by reproducing the report with a full Xenium project, using the two linked videos to inspect the segmentation triangulation, global marker controls, and cmd-A hang. Compare behavior with a downsampled or single-quadrant view; the issue is done when the rendering and global controls work reliably without the software hanging.
