Somehow my point light looks weird

Somehow my point light looks pretty weird with setShaderAuto() on (with git master / panda 1.10 from a few days ago):

In comparison to the spot lights, it has weirdly very sharp shadow borders and there are large weird blocks of shadow that shouldn’t be there (e.g. look where the wall meets the floor where there’s a weird extruding shadow part towards the downright corner of the image). Spot lights on the other hand work perfectly fine.

Is this likely something I configured incorrectly, or a setShaderAuto() bug?

The image gives me a 404. Could you attach code to reproduce the issue, too?
