After update kteatime to version 16.08.1 systray icon was restored with kde4 and did not fit the Plasma 5. I think it's better to undo the change and let it be a nice icon that corresponds to the Plasma 5, although it will not be a progress bar. Reproducible: Always Steps to Reproduce: 1. Update kteatime to version 16.08.1 2. Run kteatime Regression commit: https://bugs.kde.org/show_bug.cgi?id=279222 Icon before: https://quickgit.kde.org/?p=plasma-framework.git&a=blob&h=e22d98e21b553fa7669167517c02032078c14a0e&hb=16b478a8275f7718f13f6d29a0f6a6caafbc78f8&f=src%2Fdesktoptheme%2Fbreeze%2Ficons%2Fkteatime.svgz Icon after: https://quickgit.kde.org/?p=kteatime.git&a=blob&h=f53048c3c19f91a198de653add8889225f8c3a7b&hb=7c93786615bae868b6412a875d9010b06b5380d1&f=data%2Ficons%2F48-apps-kteatime.png
Tomasz, I don't think kteatime is that well maintained, so you should probably try to do the change yourself otherwise nobody will do it...
