Recently (not sure exactly since when), both trext-ui and contactlist just show a generic icon of a window with a triangle in it in the task manager, instead of their actual window icon. Not sure if this is a bug in the task manager or in KTp, but only ktp and Kontact are affected of those that I tried out, other applications (both Kdelibs 4 and KF5 based) work fine. Reproducible: Always Steps to Reproduce: 1. Open contactlist or text-ui 2. Look at the task manager entry Actual Results: Icon is a generic window icon Expected Results: Should be application-specific icon
Thanks for the report This was a change in Plasma 5.4 iirc in the Task Manager. I think it got fixed already but I'll let Eike confirm.
