Created attachment 118000 [details] a screenshot of the popup with previews enabled The previews of the latte dock plasmoid are not working anymore since update from yesterday. There where many updates and it was not the update of latte-dock itself (tried this first). It is now only showing the background of the preview - no icon, no text, no window. STEPS TO REPRODUCE 1. upgrade 2. start latte dock 3. hover over the an opened application OBSERVED RESULT empty preview popup EXPECTED RESULT filled preview popup SOFTWARE/OS VERSIONS KDE-Neon 5.14.5 Ubuntu 18.04.2 KDE-Plasma-Version: 5.14.5 Qt-Version: 5.12.0 KDE-Frameworks-Version: 5.55.0 Kernel-Version: 4.15.0-45-generic
1. Close Latte and run it from the terminal with "latte-dock -d" when the preview is appearing do you see any errors in the command prompt? 2. Is your compositing enabled ? 3. Add a plasma panel, does previews appear correctly for the plasma taskmanager?
1. no errors are shown 2. yes, it is enabled (says qdbus org.kde.KWin /Compositor org.kde.kwin.Compositing.active) 3. Yes, they appear correctly for the plasma taskmanager
Here is the console output from the debug session: https://pastebin.com/GkZ0KSD0
You are using plasma 5.15 something tells me this is an issue with plasma 5.15... Unfortunately you must wait for 0.8.6 that will try to solve all 5.15 issues
that was the update from today - when I wrote the information in the first post it was still 5.14. but ok, lets hope 0.8.6 will solve the issue. is there already a plan when it will be released?
Just wanted to chime in that I'm having the same problem since updating to plasma 5.15. Any ETA on when 0.8.6 will be available? I'll have a go at compiling the latest code from git and see if it's fixed there.
There is now ETA I am waiting plasma 5.15 to arrive in Tumbleweed in order to fix all breaks from new Virtual Desktops infrastructure
This is happening to me also on KDE neon User Edition 5.15; updated today via APT from 5.14.5.
The problem is not related to Plasma 5.15, or at least not only to it, as this behaviour started exhibiting after the update to KDE Frameworks 5.55.0. It had this same issue when I was still using Plasma 5.14, but had upgraded to KDE Frameworks 5.55.0.
I've posted a patch here which should fix this issue: https://phabricator.kde.org/D19002 Feel free to give it a try.
