*** This bug has been marked as a duplicate of bug 378339 *** Nate, you sure? #8 0x00007ff8708c821d in () at /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 It's a qobject_cast in QWidget code. That other trace is all QtQuick I think so; the QtQuick part is in QQuickItemPrivate::deliverKeyEvent(). We saw a lot of backtraces like this in Discover, too--all traced back to the same root cause issue. However, it's quite likely I'm wrong, as you have much more experience reading backtraces than I do, so if I'm smoking crack, feel free to un-dupe it. From how I understand the issue, there was a dangling object pointer, which caused all sorts of crashes. It is very likely a duplicate. We also have bug 388414 tracking the same issue for systemsettings. Is this a widespread problem with kde? I've experiencing some lagging behaviors on most applications that works fine on the other DE's I have installed. (In reply to Matheus from comment #5) > Is this a widespread problem with kde?

It was fixed in Qt 5.9.4 and 5.10.0, but according to the bug report you're still on 5.9.5, so that would explain it. Kubuntu Bionic is scheduled to ship with 5.9.5, but in case it doesn't, I'll make sure the fix gets backported to the 5.4.9 version we do ship. You mean fixed in Qt 5.9.5 right. Okay I hope it gets fixed for the lts release! But does it have any relationship with this lagging on some applications sometimes? Oy va voy, yes indeed, I reversed the two Qt versions. Fixed in 5.95. The lag you mention is another issue that should be reported separately. Okay thanks! |
