The most recent Windows 10 20H1 preview build introduces a new transparency bug fix after the company previously resolved a similar problem hitting the Action Center.
This new fix, however, is specifically aimed at Windows Defender, as some users experienced a weird behavior with icons featuring fully black backgrounds with no transparency whatsoever.
As you can see in the screenshot here, which I took on Windows 10 build 18995, also a preview of Windows 10 20H1, all menu icons in Windows Defender feature a dark background when they were supposed to feature full transparency.
Microsoft didn’t acknowledge this problem in the known issues section of the previous Windows 10 20H1 preview builds and didn’t mention the fix in the release notes of the latest build for Fast ring insiders.
Fix included in latest preview build
As reddit user Leopeva64-2 notes, the fix is available in Windows 10 build 19008, but Microsoft hasn’t said a single word about it. I can confirm that everything is now looking and working correctly in the latest update for insiders in the Fast ring, with the expected behavior now available.
Windows 10 20H1 is still in testing stage, and Microsoft is projected to finalize it in the spring of 2020, most likely in March. According to the typical release schedule, the debut should happen in April or May as version 2003.
Bugs like these are something to be expected given we’re still in the development phase of the update, even if Microsoft never acknowledges them. The good thing is that fixes arrive rather fast every time, so hopefully a smoother experience would be provided when the 20H1 feature update reaches the RTM stage.
