Right after switching to juce8, I had two crashes related to the new renderer. Unfortunately, I discarded the stack trace right away. Sadly I just can’t reproduce the crash, despite running it the app thousands of times.
How well does JUCE8/Direct2D work for your customers PCs? Can you safely unleash this on customers?
There are certainly customers using it in production. I’m not aware of any known issues, especially any crashes, related to the D2D renderer.
Things have been improved a lot since 8.0.0. Though there are still some minor issues, such as degraded GUI performance when multiple GUI windows are open or some quirks during switching plugins. And I am pretty sure there are some improvements on the current develop branch.
My plugin only uses pure JUCE painting calls. Using OpenGL might be a different story though. There are some related posts on the forum
