Description fililip 2025-09-19 09:33:13 UTC
SUMMARY
Text-only sensor widgets are empty after booting into the 6.5 beta. Toggling between another display mode and text-only brings it back again until a relog. Other appearance variants do not seem to trigger this behavior on relog, for instance the network usage one (graph with text) or the color grid.

STEPS TO REPRODUCE
1. Set up a text-only sensor widget with some sensor entries (like GPU VRAM or RAM usage)
2. Log out
3. Log back in

OBSERVED RESULT
The contents of the widget are gone while the title remains

EXPECTED RESULT
The contents of the widget remain visible

Adding a me too here
Notice Arch uses Qt 6.10 beta as well on the kde beta/unstable branch, so maybe Qt related?

I can't reproduce this either

However we have a somewhat related bug report when it comes to system monitors losing information, maybe it may help with this case as well: https://bugs.kde.org/show_bug.cgi?id=508184
