Hallo, > > what ppc model do you have? > An AmigaOneXE with a PPC7455/G4. I think up until now this bug (i.e. #415543 and 426433) has only occured with old world macs (<=G3). As you have a new world mac (G3=>) and have similar problems it might be a good idea to add your information to the already existing bug reports (or the upstream bug report: https://bugs.freedesktop.org/show_bug.cgi?id=11073) Rob Homsi
