Issues with figure rendering between matplotlib and ultraplot

[lixuan-code]

I'm very sorry to bother you, but this problem has been bothering me all day and I am urgently seeking your help.
If you reduce it, the same drawing code, just because I changed plt to uplt, everything has changed. Uplt seems to have taken the initiative to add rendering to polomesh().
Can you tell me how to solve it?

I seem to have identified the problem and need to add edgefix=False, when using pcolormesh to solve it. https://github.com/Ultraplot/UltraPlot/issues/136#issuecomment-2782360791

Hi @lixuan-code

I have a hard time seeing the difference between the two images, what is causing the issue exactly? The two look the same.

I spot a minor difference between the center crown.

Sorry for the inconvenience caused. The details are as follows. It can be observed that the pixel resolution in the right image is coarser compared to the left image.
This is indeed difficult to detect, and I apologize again for any inconvenience caused.

do you have some test code to play with? Not sure what could be causing this tbh, I believe we set the dpi higher than mpl by default. It may be that the contours are having an edgecolor?
