P: Moving sliders causes image colors to dim and brighten

Curious though it only happened after the update. Also happens when you crop and move image around. will check into the driver.

OK, will check into that. Just happened after the update, so that is what makes LR suspect. Also happens when you crop your image and click to move around.

Yup, we've seen quite a number of people with psychedelic colours only on the image, usually fixed by a driver update.

Only happens on image, no where else. tend to thing its the update. Had been using LR all night and then downloaded the update. Issue occurred only  after I downloaded and opened the update. Rest of the screen is fine. Other apps are fine. Only happens in LR.  Anyone else having this issue?

Psychedelic colours are almost certainly the graphics card or driver.
