I tested this fix on Ubuntu 22 and 24 with X11 and Wayland and the fix works except for two minor notes: 1. With old IM suggestion window it displayed the text we enter in the choose box as well as in the text area itself interactively which allows easy editing if you, for example, made a typo - you can use left and right arrows to navigate within the entered text and fix the typo. With the new style IM suggestion popup there is no visible cursor in the preview string and while it is technically possible to navigate with arrows within it to fix typo the lack of the cursor makes it much harder. 2. With old IM when you start entering text and dismiss suggestion window with escape you will still have the text you entered in the text area. For example for Japanese (Mozc) IM with Hiragana input mode when you start typing you get hiragana representation in the text area right away and if you press escape the hiragana string you entered stays in the editor. With your fix no text appears in editor - only in the IM popup and if you press escape the text is gone. I do not know if this is intended behavior but it is a change of behavior and needs to be discussed. Also please take time to respond to valid technical requests from @NikitkoCent and @alisenchung - even though i like the new way of handling IM more than the old one i would hesitate to approve change that has unresolved technical questions. ------------- PR Comment: https://git.openjdk.org/jdk/pull/13055#issuecomment-2493016129
