I'm using a Surface Pro 3. I've noticed that after I use lightroom for a while (varies from a few minutes to more to sometimes not at all) I'll start to see black flickering when adjusting any of the settings in the develop tab. For example, dragging the Contrast slider will cause the screen to go black until I release the change. This is rather annoying because I don't know how the change is going to look until I've released.. it makes it very hard to fine tune changes. Restarting lightroom fixes it but this is still annoying to have to do.
Does anyone see this? Or is this a known bug? Let me know if I could provide any more details.
