very very probably a systemtray problem, i can reproduce only on panels with a systray in it Git commit f4954fb976c1995b3e047317fbb59124014a21b1 by Marco Martin. Committed on 14/05/2014 at 15:46. Pushed by mart into branch 'master'. don't compute the size we don't need avoids an undetected resize loop that hangs plasma M +2 -2 applets/systemtray/package/contents/ui/CompactRepresentation.qml http://commits.kde.org/plasma-workspace/f4954fb976c1995b3e047317fbb59124014a21b1 Martin reported that sometimes still happens from horizontal to vertical (that's Martin G for the record) Martin G knows how to get me a backtrace. Adding Martin G to CC list as he's mentioned, and marking as needs info. just right now I was not able to reproduce - will try again next time I restart Plasma Does not seem to be happening anymore. |
Created attachment 86522 [details] Bug screenshot Plasma starts eating 100% CPU and gets stucked into what seems like a half-way through resize; see screenshot. Below is backtrace, seems like some QML bindings are being updated forever. It will eventually finish, but takes loooooooooooooooooong time (and one whole core). Seems always reproducible here. #0 0x00007ff01c990cf9 in QQmlJavaScriptExpression::notifyOnValueChanged (this=0x1691b70) at
