There might be a regression like: "new setting caused activating kerning for texts smaller than 10K" (or whatever is the default). So if previously the kerning was always disabled, the new option might unexpectedly activate it. My assumption was that "it should not hurt since the text is only 10K", however, in reality, it looks like even short texts cause slowness for the old JDK. So I'm inclined to make the default 0 (always disable kerning in response text areas) for Java <17. WDYT? Vladimir
