Layer Masks Broken after Update (V 25.12)

[JustKacee]

Since updating to V 25.12, Layer masks have started breaking on layers that have an adjustment layer above them. Random white rectangles now appear is spots that should be transparent, and Stamp Visible DOES capture these rectangles so it's not just a display issue. Turning the mask on or off on the Adjustment layer doesn't help. It doesn't happen every time, and sometimes rearranging unrelated hidden layers can randomly fix it. The rectangles do NOT reveal what the layer mask is hiding, or anything that's on another layer, they're just pure white. Drawing on the layer mask moves the white rectangles around.
