Hi, I have updated my laptop to F25 (soon to be alpha) using the dnf plugin, the process was smooth and uneventful. All seems to work with some small exceptions that seem to be related: 1) Plasma takes some time to show, I use two displays and the first shows immediately, as usual, but the second takes more than a minute to show. When it shows it is complete, the problem is the delay. The panel again takes some minutes to show, as soon as it shows it works normally. 2) The applications saved in a session, like dolphin, take a long time (again several minutes) to be responsive. As soon as they are responsive they work as usual. For some reason this does not affect konsole. 3) For qt based applications (I tried lyx, texstudio, calligra stage and kmail) to open a file File->Open takes more than a minute (several minutes sometimes). When the dialogue shows the everything proceeds normally. An example of case 3) is to attach a file to this message. If I drag and drop a file from dolphin to the window that I have used to compose the message the insertion is immediate. If on the other hand I use the menu "Attach->Attach File" it takes several minutes until the file chooser shows, and then everything works at normal pace. The reason to report this bug here is because the pattern seems related with qt and the interaction with file dialogues, as other dialogues seems to be OK. FWIW I tried the last kernel that I have used in F24 (4.7.2) and the result is the same. Any help is appreciated. :-) -- José Abílio
