I can confirm that extension conflicts is most certainly a thing, and it happens to a lot of people. You haven't posted your full list of extensions for us to see. However, using logical deductive reasoning, we can assume, you have all the ones that come with Zorin at the very least, and the DPT extension could be conflicted with any number of them.
Like I've said in the past on here, I like to use Dash To Panel extension on POP OS. But in order for that extension to work, I had to disable POPS Cosmic extension. This is because the two were conflicting with each other. So that may be what is going on here.
Aravisian's suggestion to turn em all off, turn on your DPT, then turn on each extension after that, till you find the extension that breaks it, is a wise choice. Eventually, your gonna find it, and when you do, your going to say, "you have failed me for the last time, forever off you shall be"
When I installed ZorinOS16, I had to ditch all the older extensions. One I was fond of was a internet radio extension. Of course it won't work on this version of gnome-shell and there was no newer version.
But I just downloaded the extension Hanne is talking about and copied it to into ./local/share/gnome-shell/extensions folder, but it does not appear in my extensions app. Do I have to log out and in to make it visible?
Wow, had to delete the one from the extension org site. Downloaded the one from github (this is one with slightly a different name) and copied it to the ./local/share/gnome-shell/extensions folder (don't forget to alt F2 + r), so you don't have to log out/in.
Now I see it in the extensions app.
Well, I only install extensions via the automatic option through the website, I don't do manual install cause I never figured it out. Again, this is one of the areas in which I hate Gnome, cause its unnecessarily difficult for no reason.
But here's the good news. The Zorin brother's are working on Zorin OS 16 LITE right now as we speak. Were hoping they will finish and release it by next year, hopefully soon if were lucky. If you would like, you could ride this Gnome wave until then. And then once LITE is released, you could switch to that for an easier life.
Anyways, just a suggestion, not telling you to switch, just letting you know, it will be an option in the future. We all know XFCE is less painful then Gnome just in general, so might be worth your time installing, when LITE is eventually released.
I got this little puppy installed in my computer right now, its sitting with delicious 1TB of unnalocated space, waiting for OS 16 LITE install.
No really, I've tried all the options, I even moved my panel to the top. switched all the setting, but I just can't get what this extension wishes to accomplish. Well, let wait for Hanne to give some more feedback.
Oke, you install it, I was guessing you had it clinched when you go to sleep. But why not trying it out with Zorin Core, just to see how fast it starts and runs. I would even let it dual boot, test the capacity and speed.
Aravisian, I will only be making one more thread on LITE coming December, so don't get mad. I wanted to do one thread per each of the last 3 holidays. Halloween, Thanksgiving, Christmas. If we don't have LITE by Christmas, I am gonna send a letter to Santa and ask him why he hates us.
Cause IMO, there is no good reason. Because we are the best, we are Linux users, we don't cave to no greedy corporations. So, instead of a bag of coal, how about we get our LITE for Christmas. There is my optimism. Well, sort of. LMAO!
The extension works correctly in Ubuntu 21.04 which also uses gnome-shell 3.38. Opacity changed immediately. Changing the text color required log out and log in.
Gnome Shell themes tried (it worked in both):
default (whatever that is)
Flat Remix dark
