I tried the attached file.It samples heise.de/newsticker which will send a redirect and the result, which gets stored in the View Results Tree. When I open the sub results and switch between the redirect and the content sample, my GUI gets stuck.
On linux it spends a long time inAWT-EventQueue-0" #18 prio=6 os_prio=0 tid=0x00007ff961140800 nid=0x25a240 runnable [0x00007ff8c3b98000]

The result is about 700 KByte, so should trigger the kerning mechanism anyway.
FelixPS. My linux computer is currently maxed out with running a test suite and the lagging can be observed with linux, too.

Could anyone confirm, that switching between 0 and biggish (200-600 KByte)samples will inflict an unresponsive GUI?) Felix would you please share the test script? As a workaround, we might disable kerning for Java <17 by default. It looks like we might need another RC for that. Vladimir
