Comment 1 TraceyC 2024-07-18 16:17:45 UTC

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with either Plasma 5.27 (the current LTS version) or Plasma 6.1.2 (the latest released version on KDE Neon)?

I'm not able to reproduce the crash with KDE Neon

Operating System: KDE neon 6.0
KDE Plasma Version: 6.1.2
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.0
Kernel Version: 6.5.0-44-generic (64-bit)
Graphics Platform: Wayland
Processors: 2 × 11th Gen Intel® Core™ i7-11800H @ 2.30GHz
Memory: 3.8 GiB of RAM

Hi Tracey,

Thanks for looking into this. It is no longer an issue on Plasma 6.1.2

All the best,

Comment 3 TraceyC 2024-07-19 16:15:17 UTC

Thanks for confirming it works now.
