Description zini.fin+kde 2023-08-05 21:26:38 UTC
SUMMARY
"System monitor Sensor" widget that has a "Display Style" of "Grid" doesn't apply configured update interval ("Minimum Time Between Updates" in the Appearance config page) to the configured sensors.
Other styles obey the interval (e.g. 1 second instead of the default (?) 0.5 seconds).

STEPS TO REPRODUCE
1. Add a new "System monitor Sensor" widget to the Plasma desktop
2. Configure the widget with any sensor and set the "Display Style" under "Appearance" to be "Grid"
3. Set the "Minimum Time Between Updates" to something other than the default "No Limit", e.g. "2 seconds"
4. Observe that the widget updates as fast as possible, not obeying the configured update interval

OBSERVED RESULT
Sensor values in the Grid Display Style update as fast as possible (same as "No Limit" in "Minimum Time Between Updates").

EXPECTED RESULT
Sensor values in the Grid Display Style update at the rate configured in "Minimum Time Between Updates".

I can confirm this bug still exists. The short refresh interval causes a really high CPU usage, too high to use the grid layout in a plasmoid on a notebook.
