  3. Acrylic works fine on 2.2.0, including transparency settings, but white pillars/creases still visible. Is this a texture problem?

Additional context
Somehow the black mosaic effect only happens on my desktop machine and not my laptop, on my laptop 2.3.1 acrylics effects works as intended, although the white crease is still visible. Even though the two machines has identical Windows 11 versions, DWMBlurGlass versions, and same third-party GUI mod software listed above. I've tried terminating or uninstalling all other third party software, I even reinstalled Windows on my desktop machine bc I thought it might be corrupted. Because my desktop is connected to 2 monitors I tried disconnecting each of them. Nothing works. Reverting to 2.2.0 is the only way I can fix this problem.

The following is my DWMBlurGlass 2.3.1 and ExplorerBlurMica config. It is identical across two machines.
