Description Tom Kijas 2017-09-19 06:58:14 UTC

QTWebEngineProcess takes up to 100% of CPU. I am not sure whether it is bug in Falkon's implementation.

Comment 1 Michael D 2018-04-16 23:35:44 UTC

I don't get 100% cpu usage, but my cpu usage can be 2-3 times higher than with Firefox with the same page(s) open. This is with Falkon 3.0.0.

I'm having about 15% of CPU utilization of QtWebEngineProcess i5-8250U and somehow sluggish and lagging input in https://translate.google.com page on Wayland

falkon 3.0.99
Operating System: KDE neon Developer Edition
KDE Plasma Version: 5.14.80
KDE Frameworks Version: 5.53.0
Qt Version: 5.11.2
Kernel Version: 4.15.0-39-generic

Comment 3 David Rosca 2018-12-24 12:59:46 UTC

That should be reported to Qt / QtWebEngine bugtracker.
