while trying to deliver a testcase for Bug #14891 (Bitmaps with offset bits do not display correctly) I tried this patch:
https://testbot.winehq.org/JobDetails.pl?Key=1740
Two VMs reported the correct pixel as 0x0000ffff instead of 0x00ffffff. (The truly failed pixel would have 0x00010101 or similar). I'd assume that is because they use 16 bit display-depth?
Yes, both of these VMs (W98SE and WNT4SP6) use 16 bit displays.
