Quake (awinquake) or Genetic Species P96 screens now run fine with latest winuae.7z.
I'm afraid my issue is with network... I use default bsdsocket:
... and tried also SANA II emu (uaenet.device) + MiamiDX: it freezes as soon as I press Online button in MIAMI! (WHDLoad also checks for slave updates from the web at launch!)
From my usual WB + bsdsocket emu, I can run IBrowse and browse a few secs before it freezes loading sites like Lemon Amiga ??
EDIT: confirmed. If I disable bsdsocket emu (and no SANAII) WHDLoad slaves won't freeze anymore, so it's actually a network issue when JIT is ON...
