Windows 10 V1903 Acryllic-Bug (in 20H1) fixed

[German]After months Microsoft probably fixed a bug with transparency effects (Acryllic display) on the user interface of Windows 10 (but in the 20H1). Here some information, what it is about.


What’s the problem with the Acryllic-Effect?

I didn’t notice that myself, because I don’t use acryllic transparency effects on the test machines. But addressed it in May 2019 in this article. After upgrading to Windows 10 May 2019 update (version 1903), Bogdan Popa noticed an unpleasant effect. In this Windows version, transparency effects (acryllic effects) are an essential part of the user interface. However, the problem is that these acryllic effects (transparency effects) only become visisble with a delay. 

At there ist this thread, where another user also addresses the topic. This is noticeable on the desktop when working with expandable elements such as the start menu or action center. When clicking on the start menu or the action center, it takes a tick until the transparency effects (acrylic effect) become visible. A video showing this effect can be seen in this article.  

There seems to be no workaround to fix the error. You can only completely disable transparency in Windows 10.

The bug is probably finally fixed (in the 20H1)

In the linked forum thread, a user mentioned months ago that this issue had been solved with Windows 10 20H1 – and other people concerned expressed the fear that they would have to wait until spring 2020 until this really worked with the transparency effects.

This could become true, as Bogdan Popa points out in this new Softpedia article. In Windows 10 Build 19002 Microsoft the issues has finally been confirmed as fixed. This Windows 10 20H1 Insider Preview Build was released on October 17, 2019 (see Windows 10 Insider Preview Build 19002.1002 (20H1)). The following note can be found in the Windows Blog in the list of bug fixes for this build:

We fixed an issue resulting in the acrylic effect in the Action Center only appearing after the Action Center opening animation had finished.

This confirms that the delayed transparency effects are not caused by poor graphics unit or other slow hardware, but are probably software-related. Bogdan Popa now hopes that Microsoft, as in other cases, will port a fix back to older Windows 10 versions.
