Since I switched from Start 11 v1 to Start 11 v2 I have an transparency Issue with the start menu. It's always full transparent and no blurring effect is added to the start menu so it's always clean transparent.
If I enable the mica effect for the start menu it's non-transparent. If I switch off the mica effect for only 1 time the start menu is correctly blurred. But if I reopen the start menu again, it's again clena transparent.
Post from Start 11 v2.0 Release https://forums.stardock.com/523854/get;3909180:
Start11 v2.0 Menu is always transparent on my Windows 10 (10.0.19045.3636):

If I set transparency too 100% or 11 % it doesn't change at all:

If I enable Mica Startmenu is solid:

If I disable Mica then the startmenu is for one time in the correct transparency settings:

On the further attempts to open the startmenu it stays like in the first picture. Only switching between Mica on / off shows for one time the correct startmenu.
I had reinstalled Start11 v2 already and used the full removal batch script. Then I rebooted before the reinstall but the behavior doesn't change. Furthermore I use Curtains for Windows theming.

Hello,
Sorry to hear you are having issues. I've checked and I don't see the issue on my system. Tested on Windows 10, you on Windows 10 or 11? Full version number please.
Thanks

Hi,
I'm on Windows 10 Home 22H2 x64 German (OS Build: 10.0.19045.3754) and I'm using Start 11 Version 2.0.3.
As well I'm using Curtains in Version 1.19.1.
Do you need more information from my side?
Regards,
I'm using this curtains style: https://www.wincustomize.com/explore/curtains/347
I made some small modifcations on the skin:
Original:

Modified Skin:

For testing purpose I used the default Windows 10 Skin in Curtains and tested the Start Menu after an reboot but it doesn't change the behavior:

I'm using the modern style startmenu in Start 11:

Skin configuration (Should be default settings):

Skin individualization (only changing mica effect on / off and the transparency level. Other settings are default):

I have all the other submenus on default (Symbol Start until backup settings).

I can not reproduce your issue. With all your setting applied on my system I still can adjust the transparency level on my system. Refer screenshot below.

Moving forward, I believe it is best if you create your own tread since it look like this is not specifically Start11 v2 issue. It most probably, some other thing that is interfering with Start11. So, please start a new thread with all the details you post here and I will try to help you there.
Thank you,
