Color management not working in develop module on secondary display after updating to LRC 13
I use a portable Viewsonic Colorpro VP16 OLED screen as a second monitor for checking my photos against my main screen (dell u2718) while I am editing in the develop module due to the greater colour depth and accuracy of OLED monitors. Both monitors are software calibrated through displaycal and I have never had any problems with the ICC profile not working in color managed applications (including Lightroom Classic prior to the update).
When I updated to LRC 13, the colours on the second display are far too saturated on the secondary OLED display (this only occurs in the develop module). If I use the OLED screen as my main monitor then the colors are displayed correctly. My guess is that something has gone wrong with the way lightroom applies colour management for secondary displays in the develop module.
If anyone else is having this problem or knows how to fix it I would really appreciate the help. I couldn't see anything else on the forum about this but I may have just missed something.
