We have fixed an issue that was introduced in 1.1 when we added image filters; I think this will solve this issue as well. We'll likely make a release next week; please stay tuned!
Thanks for your help inukshuk. Long live Tropy !
OK I hope these issues are fixed in Tropy 1.1.3. Here are two screenshots comparing 1.1.2 and 1.1.3 on a Retina MacBook. Please let me know if you notice any other zoom quality issues!
Many thanks Inukshuk! This is a big fix!
Thank you so much inukshuk !
