Bridge graphical glitch on Fedora KDE wayland

[marcdus]

Expected Behavior

Seeing the bridge client correctly.

Current Behavior

It launches, including a working window and status bar icon, but with a graphical glitch.

(note that the displayed content is whatever was displayed before launching the app. In this case it's the KDE startup logo)

The CLI interface works as expected and I can send/receive Mails with Thunderbird.

Launching the GUI via command line gives the following output (redacted for anonymity):

I have been experiencing this issue on the Flatpak for a couple of weeks.
Same environment and software versions.

Tested this with plasma 6.2 beta and the problem is the same, but also a bit different. Instead of a glitched graphical window. I instead get a qml error popup window. Like other commenters have stated though the backend works fine and I can still send and receive mail. I just can't open the window.

Environment.
Arch
KDE Plasma 6.1.90 (6.2 beta) w/ wayland
Nvidia driver version 560.35.03 (nvidia-open driver) the newly recommend default for newer cards. Graphics card is an nvidia rtx 3080

This issue is also affecting me on Arch Linux with KDE Plasma 6.2 under Wayland. The Bridge backend works just fine, but when I try to open the GUI window I get a "qml error" popup window.

Unlike the other users I have an AMD GPU.

[Zindswini]

Still occurring on Fedora 41. No QML error popup, just a window that fails to draw as in the original report.

Plasma 6.2.3
Qt 6.8.0
Nvidia Driver 565.57.01
