Package: konqueror
Version: 4:15.12.1-1
Severity: normal
Dear Maintainer,
I have a high CPU load with no recognizable activity after certain web
pages are loaded. Simple ones (90ies style, like blog.fefe.de) don't
have any problem. As soon as I open a page with some more contents
the load starts increasing. JS might be the trigger but I don't know for
sure. Anyhow, this activity consumes about 20% of a core and opening
multiple tabs of that kind amplifies that load. In strace output (see
below), it looks like crazy looping over some file descriptor, which is
an eventfs according to lsof.
The activity remains when I close the last konqueror window. I have to
actively kill the process to make it stop.
Note: the cause might be some library bug. I started seeing other
effects in the last weeks with Iceweasel and even Chromium, although it
looks differently for them - not much CPU load but UI widgets seem to
freeze and don't respond to user input, although basic redrawing still
works; for Chromium, a "unresponsive script" window appears after a
while and then the redrawing stops there with artifacts and the main
window get stuck and grayed out after.
Best regards,
Eduard.
