So I finally removed Pixelmator from my macOS laptonand going all in with Pixelmator Pro. Its really nice and makes simple cropping and color corrections a joy.
I noticed a small bug. When I take, for example, a photo that I want to crop a photo to a 16:9 ratio using the crop guides and or change the image size to 1920 to 1080. Sometimes I get an extra pixel added so it becomes 1081. Not sure if its a rounding error or if the error is replicable, but I'm getting this oddity quite often. I can change the Canvas size to get the 1080 so short term I got a fix but thought better to let you know about it in case others run across the same bug too.
Is something not working like it should? Let us know.
