So I have been installing 15.04 as an upgrade path from 14.10
Issues I ran into (or still run into):
* The Air theme (Desktop Theme) doesn't apply very well to the Panel (taskbar) its text is half invisible.
* Applying Breeze Dark doesn't seem to work at all
* Applying an Icon theme apparently only works after logging out and in.
* The Oxygen theme has buttons on the task bar that are so badly visible (small icons, unreadable text) that it is hardly usable (I cannot even distinguish Firefox windows from anything else so readily).
* The Glassified theme is for me a very good replacement, except transparency is again a problem: everything is too transparent.
* The Air or Air/Oxygen Application Settings->Window Decorations theme has also transparent title bars and so on, badly readable.
* Most window decoration themes seem to be transparent. I am currently looking at a theme with a title bar that as a 50% translucency text behind it, making it rather hard to read what's in front. Most windows on my system are always maximized. Sometimes when that is not the case the text behind it can be more visible than the text in front. I really don't know or see what is so attractive about these high levels of transparency. I call it idiots. That theme I am currently using is Xenon. Pretty nice though.
Oxygen icons work well but currently I seem to be having a mix. All of this is easy to reproduce, my system is not all that special.
It makes it hard if you have to log out and that closes all your windows, but what's more I don't know even if logging out works without me killing SDDM. From a TTY. This last time it killed the whole system, screen went blank, first time it's really been this unresponsive. Had to shut it down. No TTY anymore either, but that was because I ran /etc/init.d/sddm stop. Weirdness. I wonder when I will find how to log out of this thing and Live.
The icons are now a mix even when it is not necessary. Many control are still (because of Glassified? but Breeze had the same) unusable to a large degree because of all the transparency. I really don't know what the thought is behind trading in usability for looks. This transparency is not configurable anywhere. The glassified theme looks very nice for the panel (taskbar) but the menu (Kicker?) is also quite unusable again unless I have a clear desktop. I don't know why I am currently getting a mix of colourful icons (Oxygen) and stale flat black-and-white icons (Breeze).
I had installed a window decoration theme which caused the application to crash. Now my logout screen is highly unusable. It is tearing (like the Breeze one also does) and without any display of text or anything. It seemed to have been possible to read something on it from a different angle. However, mostly I cannot achieve a re-login or the startup of SDDM is just really really slow.
