[Bug]: Recently updated Signal fails before it is fully initialized. #397
Description
What happened?
After today's update, Signal fails to completely start.
A window appears with the blue Signal logo in the middle, and stops there. Clicking on menu items, e.g., 'file' causes faint drop-downs to appear.
This is on a fully updated Kubuntu 25.04:
Operating System: Kubuntu 25.04
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.3
Kernel Version: 6.14.0-33-generic (64-bit)
Graphics Platform: Wayland
Processors: 32 × AMD Ryzen 9 3950X 16-Core Processor
Memory: 62.7 GiB of RAM
Graphics Processor: llvmpipe
The previous version of Signal worked on this system.
What should have happened?
Signal should have started normally, with previous chats, etc.

**Minimize to tray**
Per the request of the Signal developers, this snap does not use the system tray by default. This
is disabled by default per the request of the Signal developers, because system tray support is
not stable. Set to `false`, Signal will stop when you close it and will not have a system tray
icon. You can enable it by running the following command.
snap set signal-desktop tray-icon=true
