I'm using Radeon r290, Windows 10 64bit, Radeon Software Version 18.2.2, Adobe Lightroom Classic CC 7.2. Using Graphic Processor results in black screen in place of edited photo. It triggers after switching from library to develop module or randomly after some editing. Same thing is mentioned on Adobe forum PROBLEM:Black screen in Develop Module | Adobe Community but provided solution is to disable graphic processor... I did tried previous Radeon software version without any luck.
