Hi blast,
your team did a good work, course the v2.4.2 ran perfect at my Mid 2011 iMac with 27 Inch Display, Intel Core i7 3,4 GHz processor, 8 GB RAM and AMD Radeon HD 6770M.
At Saturday, December the 5, 2015, I migrated all software (and the user accounts) to the brand new Late 2015 iMac with 27 inch Retina 5K display, Intel Core i7 4,0 GHz processor, 32 GB RAM and AMD Radeon R9 M395 2048 MB.
The v2.4.2 was nearly the only software which made problems (no problem
, showing big colorful stripes running up and down the display. I tried to change all display options but there was only a change in the colors and the running direction.
Your 2.4.4-RC2 has none of the display problems. You can change the resolution to the (sensational) 5120 by 2880 pixel -- it works perfect.
So many thanks for the good work and nice greetings from Munich, Bavaria.
