Created attachment 76434 [details] The text is very hard to read The new Air theme in 4.10 has lighter transparency than the Air theme in 4.9 and earlier. Although this is not a bad idea per se it produces some issues with dark wallpapers because black text on a dark background is hardly legible. Some widgets such as the Clock widget use white text with a drop shadow around anyway, but some don't. E.g. the text on the task manager widget is barely readable (see attached screen shot), especially when the window is minimized. I file this bug report against Oxygen because I think this needs a general solution and not a solution on a "per-widget" basis. Some widgets such as the Folder View widget use a white gradient behind text, which is one solution to the problem, but probably not the prettiest. Whatever solution you choose, the behavior should be the same throughout all widgets.
Thank you for the bug report. As this report hasn't seen any changes in 5 years or more, we ask if you can please confirm that the issue still persists. If this bug is no longer persisting or relevant please change the status to resolved.
In Plasma 6 Air doesn't use disabled text for inactive windows so this shouldn't be a problem anymore. Please reopen if you'll be using Air when it lands in versions 6.7+ and still have issues with legibility.
