I’m using the latest version of RT for a duel boot box, i.e. an RT setup on Ubuntu and a RT setup on Win 10 both set to work on the same folder, files and pp3. Oddly the white balance tint and temperature seem not to be aligned.
By not aligned, I mean out of sync. What you see under Ubuntu is not what you see under Windows.
As to versions, I’m using Dariusz Duma’s latest compiled version 1:4.3+git20160914-378~ubuntu16.04.1. And on windows, RT 4.2.1148 for Windows Vista/7/8/10 64-bit - fast.
As to loading the ICC profile, nope… I’ve not done that.
I’d check and see what ICC profile each OS is using, especially if you haven’t calibrated your monitor. I wouldn’t expect them to look the same at all.
That clearly looks like wrong black levels are used in the windows version. The windows version definitely is gtk3 and behind your linux version for some commits. Can you upload a raw file to filebin.net, please? I’ll have a look then tomorrow.
