I have a 3 monitor setup. My center monitor is a 4K Asus Pro Art. and the two flanking monitors are Dell U2410’s. All other software like Darktable works fine when all three monitors are enabled on my Linux Mint system. Gimp struggles with screen redraws and it is making things slow. The problem goes away when I disable the flanking monitors. My system: HP Z820 workstation. Two Xeon processors and 128 GB of RAM. Graphics Card is a Radeon 580x with 8GB VRAM. Any help appreciated!
