Description Gert Oja 2024-03-29 10:18:08 UTC

SUMMARY

When switching from a page that is loading, the loading gear icon stays on screen for that page, covering it until the System Monitor is closed again. The loaded page is visible as a small sliver at the top of the view.

STEPS TO REPRODUCE
1. Open System Monitor
2. Switch away from pages, e.g. Applications or Processes, while they are loading

OBSERVED RESULT

The gear will appear, covering the entire page except for a small sliver on the top.

EXPECTED RESULT

fast.webm – clicking rapidly through not-yet-loaded pages

I can confirm the issue. When rapidly clicking through pages, several pages might get affected. I attach a screencast (fast.webm) showing the problem. Another screencast (slow.webm) shows the expected behavior when clicking slow enough.

It seems this may have been fixed with https://invent.kde.org/plasma/plasma-systemmonitor/-/commit/2584f65a33c74ea4b3479af82143797ecefff04f , at least I can no longer reproduce this but the problem does appear again when reverting that commit.
