Tried the Explorer transparency option with Play style.  Works, but only after 1-4 seconds of delay post-launch of Explorer.  Sometimes trans effect won't appear at all until clicking in another window or the taskbar.  Win10 Pro v2004.

Thanks, basj.  Latency issue remains after explorer restart and with standard blur, acrylic blur and basic transparency.  No wallpaper manager, Deskscapes  or WallpaperEngine.  Only other SD app running at the time is Start10.  It's a Dell Optiplex 3060 desktop with OEM Intel video.

Is your computer automatically opening up some explorer windows on login, or are you manually opening these windows?

PLEASE make the "Transparency with Blur" available in Next WB Update just like for Curtains ! ! PLEASE !     

(-Hoping someone will actually answer me)

Current situation, still having not run purge/reinstall:

Over time, the latency of transparency on initial opening of an explorer window has shortened to a few milliseconds with an initial flash of white in each frame.  It seems that if a sufficient period of time has passed since last launch the initial launch trans works.

If I close the initially-opened explorer window and immediately launch Explorer again, transparency will not appear until a click event, on Explorer itself, another window or taskbar for example.

If I launch additional instances of Explorer after transparency is active (either with initial launch or a click event), transparency only appears in the additional instances with a click event.

Tried to do a SS of 2 Explorer windows side by side showing this, but just pressing the CTRL key triggers trans to appear in the second Explorer window so add keystrokes to clicks as triggers for the trans appearing.

I'm not knowingly running folders as a separate process; not sure where that setting resides.

Thanks again, Neil.  Hope this is of some help.

Is that the same machine you had to exclude universal apps on before?  I assume your other computer doesn't have such an issue?

Regarding the transparency, I wonder if the files were not replaced correctly.

Uninstall Curtains, reboot and then install the beta.

That is very strange as nobody else seems to be experiencing those issues with universal apps.

What other apps do you have on both, AV apps, other security apps, other third party software etc?

Is the Chicago theme false advertising? It clearly doesn't exist and doesn't have a fingerprint left behind anywhere on these or other forums.
