[14.20] Striped pollution map

I've been dealing with this issue where my pollution shows up only in stripes. I have the issue with single player and also in multiplayer games hosted by another player. Used to not be this way. Before, I would have all columns filled with pollution. Playing a ribbon world in the screenshot but infinite map games have the same bug. Vanilla game with no current mods installed, see picture. Tried a few Bob's mods in the recent past but nothing installed currently.

Tried:

Verify game cache
Uninstall with file backup, reinstall
Changing graphics settings

Please post a screenshot with show_pollution_values enabled in the debug settings (F4 > F5) and upload the save file.

Save file would be very helpful.

Steam updated before I was back at my computer to upload. Loaded Ribbon world which is now fine with pollution. Attached along with another map which I haven't loaded since the update in case that helps.

I don't see anything wrong with the last save file from you uploads either.
Please upload the save that shows the screenshot with the issues and have the player right at the scene.

I mentioned in my previous post that updating automatically to 14.21 looked to have fixed the issue.

I forced a downgrade to 14.20 and see the issue in the multiplayer map. Saved it as is in the screenshot and have uploaded again. I can replicate the issue in any save or new game that is 14.20.

Interestingly it renders perfectly for me in 0.14.20: http://imgur.com/a/Nn6Sn
