Description Dipta Biswas 2022-01-21 09:00:03 UTC

SUMMARY
Akregator uses QtWebEngine to render feeds, but those don't close even after closing akregator properly.

STEPS TO REPRODUCE
1. Close akregator from menu or using Ctrl+Q
2. Check processes using ps aux | grep webengine and ps aux | grep akregator

OBSERVED RESULT
ps aux | grep webengine

EXPECTED RESULT
Only grep process should be shown. When I close falkon, there is no such residue of adChromium. Akregator should work similarly

ADDITIONAL INFORMATION

Comment 1 pixelplanetdev 2022-05-07 23:52:40 UTC

Can confirm.
However, it does not happen every single time.

The WebEngineProcesses are also running when Akregator is only in the system tray.
