You see this effect in Lightroom Classic or after in Photoshop?
First, try disabling GPU in the preferences (Preformance tab of the affected application). Any better? If not, in Photoshop, go to Preferences > Technology Previews... and check "Disable Native Canvas" - then restart Photoshop. Better? If not, recalibrate and build a new ICC display profile, the old one might be corrupted. If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile. If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.
