Blue square as shown on a wayland session

Description of problem:
On the new F34KDE isos (until 20210227) when rovering the mouse over the icons of active windows on the panel, instead of a miniature of the real window, one sees only a blue square (see image attached)


Version-Release number of selected component (if applicable):
ISO => Fedora-KDE-Live-x86_64-34-20210227.n.0.iso
Frameworks = 5.79.0
Qt = 5.15.2
Plasma Desktop = 5.21.0-2.fc34.x86_64
Kernel = 5.11.0-156.fc34.x86_64

How reproducible:
Allways on wayland
On X11 it shows differently, not a blue square but a big icon instead (as shown on image attached)


Steps to Reproduce:
1.Start system
2.Open some program from the menu
3.Rover the mouse over the icon on the lower panel

Actual results:
Wayland session = blue square
X11 = big program icon


Expected results:
All sessions = a small image of the actual window (thumbnail)

This image is from my F34 kde installation I branched from rawhide last month.

Comment 3 Geraldo Simião 2021-03-29 16:01:38 UTC
Today I tested a F34kde spin iso (20210329) and it worked fine, as it suposed to be. Tested too older iso (20210323) and it's fine too.
Don't know what the problem was, but anyway, it is no more. So I will close that,
