Unable to reproduce here and we tried on three different machine. How Qt is compiled on gentoo? According to 0x00007faaf492e8e8 in QWidget::mapTo (this=<value optimized out>, parent=0xedc000, pos=@0x61a) at kernel/qwidget.cpp:3785 it is probably compiled with some optimization flags that we don't support (lines are different, this has a strange value but just before it was valid). Is it debug or release? It seems to be release build but the case is perfectly handle according to the code.I would say that the compiler is trying to do some magic that we don't control. I close the bug because it seems to be related to Gentoo... Gentoo issue i would say... My CFLAGS are "-march=nocona -O2 -pipe -ggdb". ggdb is there having followed the guidelines for useful bug reports on the techbase. I did compile with the debug use flag, but that broke virtually everything I had (I was getting spurious output all over the damned place), so recompiled again without that useflag. They told me to submit this upstream when I asked in IRC. I'll submit another bug downstream and link to this one. Are you using nvidia drivers? with backing store enabled? Closing correctly.valdi |
Version: (using KDE 4.3.0) Compiler: gcc-4.3.2 OS: Linux Installed from: Gentoo Packages Every time I use a screen corner to activate 'show dashboard', plasma crashes. Steps to reproduce: 1. Set a corner via 'screen edges' in kcontrol to 'show dashboard'. 2. Move mouse to that corner. Frequency: Happens every time.
