Partial screenshot of my desktop with widgets that used to be fine.
SUMMARY
Widgets being rendered incorrectly, overlays, charts randomly blank. QT issue?
Please see screenshot attachment. I've used monitor widgets on my desktop for
years but suddenly over the past few months an update has caused widget
rendering issues. Text is randomly redrawn without clearing the buffers,
charts randomly go blank, etc. Sometimes forcing a refresh of a widget or
changing the settings causes it to refresh and draw correctly but it would be
nice to have an actual fix.
STEPS TO REPRODUCE
1. Place a monitor widget such as CPU temp, cpu load, network, disk etc into
desktop.
2. Reboot or watch as occasionally sessions lack half of your charts and
numbers are refreshed badly.
3. Change a network monitor or setting in one of the widgets and confirm.
Refreshes may fix it temporarily.
OBSERVED RESULT
Check screenshot attachment. Charts are missing and numbers are overdrawn.
EXPECTED RESULT
All charts should render correctly as they have in the past. Numbers should
clear buffers when redrawing so you don't see the previous numbers behind.
