Hi,
I recently acquired a Dell XPS 13 laptop with a QHD+ display. I installed RawTherapee and it seems like everything is upscaled (screenshots available at the end of this jira case). UFRaw in contrast seems to have the correct scale. Does anyone know how to solve this problem? OS: the latest version of Fedora with Gnome desktop. I only found one article mentioning that Fedora would scale everything by 2x.
Ok, the conclusion seems to be that RawTherapee currently lacks support for HiPDI (Retina) displays. There is a ticket to address this: 3547
