Strange lines appear when using pcolormesh with nonzero alpha value #480
Comments
This is a known problem referenced in matplotlib/matplotlib#1188 and, I think, more comprehensively in other old matplotlib issues that elude my quick attempt to search for them. We have found no general good solutions. |

When plotting data using pcolormesh on a basemap projection (or a cartopy projection) I notice strange lines appear when I set the alpha value to less than 1.
Example code:
The output shows strange lines appearing:
If I instead set alpha=1 the lines disappear and the behavior is as expected:
Any ideas on what the issue is or how to get pcolormesh to work with a nonzero alpha value?
