Photoshop Glitch where edges of layers disappear
Since updating to the new version of photoshop, I am having an issue where edges of layers in photoshop abruptly disappear. For example, the top 10px of my text layer will disappear. Or the left 10px of my image layer is gone. If I try to paint/edit the missing portion, I can clone from it, and it may temporarily reappear, then disappear again. This is particularly problematic when I save an animated gif, and the missing portion appears in some frames and not in others, creating a flashing effect that draws attention to the glitch. (Yes, the problem persists when I save a jpg or other file from my PSD, so it's not just a screen/display problem.)
Photoshop version - 20.0.0 release, CC 19.1.6
macOS High Sierra 10.13.6
Example: The curved edge of this image layer is missing.
