--- Comment #1 from Jörg Höhle hoehle@users.sourceforge.net 2009-06-23 07:32:12 --- Defect a) is gone in wine-1.1.23 on the nVidia Mac OS (with ORM=backbuffer). The picture is beautiful. The defect remains on the Intel i915.
b) [horizontal garbage line] is still present on both machines.
I discovered another area where moving the mouse refreshes pixels, on both machines: one pixel line above and below the horizontal pop-up for the scene (track?) selection menu, beneath the scene view.
