please try adding

Q_ASSERT((n>1 && last > 4) || last > 5);

could be that the different texture layout creates textures < 64x64 and your GPU/driver doesn't like that.

In case that happens you'll get a crash. To avoid that and try a fix instead

if (n > 1)
    return 1 << (qMax(last,5) + 1);
return 1 << qMax(last,6);
