Adobe Illustrator CC 2015 enables GPU rendering by default. While this can be a lot faster, it apparently has significant detrimental effects on the display of some graphics. That’s kind of a deal-breaker for a graphics application.
Here’s a gif showing the difference between GPU rendering in CC 2015 and the previous renderer from CC 2014:
What is going on with those GPU-rendered strokes and edges? They look like they’ve been through a fax machine. Lines aren’t even representing their true length, let alone the stroke-width irregularities.
This isn’t just an edge case, the visual artifacts probably appear because GPUs want everything to be triangles. This is a huge step backwards.
Thankfully there is a workaround: Disabling “GPU Performance” (irony) reverts Illustrator’s renderer back to something that still works.
Note: I tried Adobe’s troubleshooting suggestions without success. How does something like this make it out of QA? Adobe should really consider offering a public beta period so bugs that completely compromise the application can be fixed before wide release.
Also noted: Adobe Illustrator CC 2015 display anomalies, GPU smoothing bug
Update: More:
Path joins are filling in. Even zoomed. These triangle shaped fills don’t exist in the file:
Now I’m sure! Nobody tested #illustratorcc2015 before shipping. Here’s a proof. Basic functions just don’t work: pic.twitter.com/A7YivbFqX3
