| OK, after the downgrade, the delay in the KMenu is gone for sure. So, that's a big relief! |

I must say that it's only slow when I do a reboot/logoff/shutdown.
Takes more than a minute before the system reacts.

| That sounds like a Qt-5.6.0 bug that will be fixed in .1. |

Qt-5.6.1 is out! I will be building it in the next hours and report back.
Let's hope the issue is solved  |

| The delay certainly didn't go away for me, but I haven't yet tried out with a new profile. No delays after updating from Qt-5.5.1 to 5.6.1 on my main system though. |

I upgraded from 5.5.1 to 5.6.1 and I still get the delay.
What do you mean with the new profile, genstrom? |

It seems that with latest plasma releases (>=5.6.5) from KDE overlay, QT 5.6.1 is now mandatory.
i.e. kde5.eclass
| Code: | if [[ ${CATEGORY} = kde-plasma ]]; then
if [[ $(get_version_component_range 2) -eq 6 && $(get_version_component_range 3) -ge 5 ]]; then
QT_MINIMAL=5.6.1
fi
if [[ $(get_version_component_range 2) -ge 7 || ${PV} = 9999 ]]; then
QT_MINIMAL=5.6.1
FRAMEWORKS_MINIMAL=5.23.0
fi
fi

| Is a month a typical release period for qt-5.6.x releases? I would wait for 5.6.2 before I got plasma-5.6.5. |

Hi! I think I solved it!
I couldn't resist the temptation of upgrading to plasma 5.6.5 and... it didn't work
However, after some thinking, I started to play around the the graphics related flags of Qt, as I thought it might have something to do with the compositor. I removed gles2 (USE="-gles2" in make.conf). Recompiled the whole thing and It worked!
Please, let me know if it also works for you and we can mark this as solved/workaround. There is still a bug somewhere, but I am not sure is worth spending much time on it.
P.S: If it doesn't solve it for any of you, we can start comparing use flags. |

| Confirmed. Getting rid of gles2 flag in dev-qt/*, kwin and plasma indeed fixed the delays! |

But isn't that too much to give up to workaround a problem?
Is there a bug filed for this somewhere? |

| I don't see why, after all you go back to 'full' OpenGL. |

So, we have blocks to deal with now... e.g. polkit-kde-agent wants qtwidgets-5.6.1.
Looks like I need to unmask and disable gles2? |

Its not easy. There are other packages which force mesa[+gles2] if I enable 'opengl' flag. I want 'opengl' support globally. And I can't give up on packages like qemu, which is forcing gles2 on mesa.
So, where do we go from here? |

| It's no problem to have mesa[gles2], you just don't build Qt/Frameworks/Plasma with that flag. |

Please show 'it'
No one can help you at that level of (non-)information. |

Only issue is that it does not give me much info:
| Code: |
# time emerge -pvuDN --tree --verbose-conflicts world
These are the packages that would be merged, in reverse order:
Calculating dependencies ..... ... done!
The following USE changes are necessary to proceed:
(see "package.use" in the portage(5) man page for more details)
#
>=dev-qt/qtwidgets-5.6.1 gles2
#
>=dev-qt/qtgui-5.6.1 gles2

Well, what were your steps towards removing gles2 use flag? Is it enabled in make.conf? Is it set or unset in package.use?
| Code: | $ emerge --info | grep gles2
$ grep -R gles2 /etc/portage/package.use |

Removed in make.conf and added to package.use for mesa.
| Code: |
# grep -r gles2 /etc/portage/
/etc/portage/package.use/all-others.use:# dev-qt/*:5 -gles2
/etc/portage/package.use/all-others.use:media-libs/gst-plugins-bad -gles2
/etc/portage/package.use/all-others.use:net-libs/webkit-gtk -gles2
/etc/portage/package.use/all-others.use:media-libs/mesa g3dvl -llvm xa gles2
# grep gles2 /etc/make.conf
crash-reporter qt5 systemtap wayland bluetooth x265 postproc -libav gles1 gles -gles2 vaapi
# emerge --info | grep gles2

Remove gles, at least for kinfocenter, that's what is forcing qtgui[gles2].
No need to switch off gles2, it's not on by default anywhere. Not sure what you do with gles1 either. |

| Any ideas on why portage is not telling me who is enforcing the gles2? It has always told me that in the past. |
