Disappeared icon

SUMMARY
After plugging in the USB modem and setting up the providerm, the icon disappears from the bottom panel. I can see for a breaf moment the signal bar and a U (presumably UMTS)

STEPS TO REPRODUCE
1. Connnect the modem
2. Setup the internet at NM settings:
  - + button
  - mobile broadband
  - business as usual

OBSERVED RESULT
While the modem is connecting (blue circle in the panel icon) I can see the icon behind, but as soon as the blue circle disappears it looks like the attached screenshot.

EXPECTED RESULT
See the signal bar with the U indicating a connected modem.

Comment 1 Nate Graham 2021-03-19 02:07:02 UTC
What are your icon theme and plasma theme set to?
Comment 2 Andrés B.S. 2021-03-19 02:18:41 UTC
Both are set to Breeze Dark.
Comment 3 Nate Graham 2021-03-19 17:28:17 UTC
Hmm, darn. That means the bug is in plasma-nm, for either
1) trying to use an icon that doesn't even exist in the Breeze icon theme, which generally has the widest assortment of icons of any icon theme.
2) unsetting the icon when it shouldn't

Icon appears while loading

The icon appears while it is connecting so I think it is more likely to be option #2.
At times, the network type changes from UMTS to HSUPA/HSDPA.

Comment 6 Nate Graham 2025-06-24 19:44:48 UTC
Thanks for the bug report, and I'm sorry we weren't able to figure this out. Can I ask you to see if the issue is still happening in Plasma 6.4 or later?
