Thanks for the extras information, the text cut is again an issue about windows zooming, seems like neither java version handle it perfectly after all. You can try to change the font size in the Icy preferences, i think it can help but definitely the window desktop zooming feature (to deal with ultra high resolution screen) bring many appearances issue in Java.
About the image loading problem, in the next version the grouping will be done depending the "loading type" mode selected in the load options. Still, it would be nice if you could provide us a small image sampe so we can test it and be sure it works as expected :) Thanks again.
Best,
