The background of work area flash

[Merry_introvert5E06]

Recently, I found my lightroom's background of work area and the dark part of my photos started flashing, when I change any parameters. This problem also takes place in Photoshop ACR. But, if I disable GPU in “preferences-performance”，this situation will not happen again. I hope that someone have some ways to fix it. Thanks!

If disabling the GPU resolves the flashing issue then you already have the best fix currently available.
