There's no such thing as mica in Windows 10.

[Mukul1127]

Yes, I know but I though the custom effect emulates it instead of actually using windows api

[timea-techgirl]

I have the same error. It worked fine in v2.0.1

[ALTaleX531]

@timea-techgirl Unrelated to this issue, your video card driver was probably upgraded not too long ago.

[timea-techgirl]

My nvidia graphics driver is 398, final version from my manufacturer. I haven't upgraded it because everything works. Should I upgrade to fix this?

[ALTaleX531]

@timea-techgirl The problem was only caused by upgrading the graphics driver a short while ago, it is a bug in the GUI program and you can continue to use DwmBlurGlass and not need to do anything.

[ALTaleX531]

@Mukul1127 Nowhere do we state that we will emulate the appearance of mica, so this is not a bug.

But I haven't upgraded my driver. It has been the same since I installed windows. This error doesn't exist in v2.0.1

[ALTaleX531]

@timea-techgirl That's just because you don't happen to have encountered it, in fact the problem has been around since 1.0.0.

Sorry I didn't see win11 only for Mica because I read "Adds a custom effect to the global system title bar."

would it be possible to at least add some simple protection to not allow user to select Mica on Windows 10?
to prevent the DWM from crashing
