Bug ID: 466502
Summary: GPU Usage/Memory shows "inf%" on Processes tab scaled
modes
Classification: Plasma
Product: plasma-systemmonitor
Version: 5.27.1
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: ho...@tensi.org

Target Milestone: ---

Screencap showing inf% with a visible chart, a blank line, and two chart
histories visible with no text. Above is Psensor readings of the "graphics" and
"video" sensors' current/min/max values.
SUMMARY
When using the GPU Usage & GPU Memory columns in the processes tab set to the
"Line Chart (Scaled to 100%)" or "Text Only (Scaled to 100%)" modes, the text
values read either "inf%", or are blank. The line charts don't seem to work
properly either.
STEPS TO REPRODUCE
1. Open System Monitor
2. Switch to Processes tab
3. In "Configure columns..." switch GPU Usage or GPU Memory from "hidden" to
"Line Chart (Scaled to 100%)" or "Text Only (Scaled to 100%)"
4. Run a GPU-intensive operation (i.e. hardware transcoding video in Handbrake)
5. Observe the columns for a moment
OBSERVED RESULT
Text reads either "inf%" or is blank; line charts appear to stay near the top
or are blank.
EXPECTED RESULT
Text should read a percentage from 0-100 based on process usage; charts should
accurately follow that as well.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.27.1
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.1.12-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-7700K CPU @ 4.20GHz
Memory: 15.6 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 2060/PCIe/SSE2
ADDITIONAL INFORMATION
My GPU is the MSI RTX 2060 Ventus GP 12GB OC - perhaps the overclocking is
breaking things? When using a System Monitor widget to show overall GPU Usage,
the percentage can rise above 100%. Cross-referencing with Psensor, it appears
the GPU usage sensor adds the "graphics" and "video" sensors together, both of
which presumably go from 0-100% (though when testing, the "graphics" sensor had
only hit a max of 70%).
