The next major version of Windows 10 is getting closer, and I installed the latest build as of today. (16288.1, v. 1709). I also use the latest WB that is publicly available. Current theme is Ubuntu 11, although it seems to lack some basic colour settings.
+ taskbar skinning works again, meaning it's not mostly translucent anymore
- I still have to exclude Firefox (64bit version at least) otherwise it doesn't launch/start -> I get the "normal" menu background/texts which is light gray on white -> really hard to see the menu texts. Also true for the bookmarks menu. Seems to be Ubuntu 11 specific though. When another theme is chosen the menus are properly coloured. So If I exclude FF I also need to have "proper" theme in use so the menus are visible.
- WB10 config has it's titlebar cut from the bottom, If I reapply the skin it's properly sized.
