[BUG] With multi-window mode, some apps or render surfaces appear translucent

Describe the bug

In multi-window mode, I realize it appears that Waydroid is rendering a transparent full desktop window layer, with the windows as sub-surfaces of this window, including the cursor. The problem is, some apps, such as 3DMark's Vulkan benchmarks, render with the display surface area as alpha 0, and the color channels appearing to be treated as pre-multiplied by alpha, so their color values are added to the pixels underneath of the Waydroid window.
