Hi, Since the last update of konsole last week, anything i do on konsole is very slow and laggy. * Everytime i switch between two konsole windows i have to wait a moment (like a second) until the window gets the focus * every commend i enter lag's - i always have to wait until the command gets executed (every command, even simple commands like ls, dmesg an so on...) * scrolling is painful (genlop -l) takes ages to the bottom. The problem is however only on konsole, anything else works as expected. The problem came with kde-apps/konsole-15.08.2 or generally with kde frameworks 15.08.2. kde-apps/konsole-15.08.0 worked perfectly well. Also xterm works perfectly well. I though to wait a week and see if the problem goes away with further updates, however it gets really annoying now and i don't know what causes those lags. I've tested following: * downgrade to kde-apps/konsole-15.08.0 (restored the ebuild) * switched the X use flag on konsole * tried it with a complete new user profile Nothing worked so far. It seems like konsole uses a "software" mode for rendering everything...

You're not the first one to report this, and I do wonder why... it's a shot in the dark, but as I can't find existing reports about this, please try to rebuild kde frameworks: # emerge -vp $(qlist -CI kde-frameworks/*) In case you don't know `qlist`, it is part of portage-utils.

I did rebuild both kde-frameworks/* and kde-plasma/* , however no change so far. I've also switch from GLX to EGL in the Compositor Settings - no change :( From the kde bug report it seems the problem belongs to qt-5.5.1. I wanted to downgrade qt but kde-frameworks/frameworkintegration-5.15 (and obviously the whole framework) depends on >=qt-5.5.1. :/ > > # emerge -vp $(qlist -CI kde-frameworks/*) > > In case you don't know `qlist`, it is part of portage-utils.

After downgrading QT (and rebuilding all kde-* packages) konsole is fast and smooth again :) I've added the upstream bug to the URL. For me the problem is solved, but i guess we should keep the bug open since the latest QT is still affected and it would be clearly a stable blocker.
Do you happen to have media-libs/freetype[infinality] as someone suggested on the bug?
I've submitted an upstream bug to Qt as it definitely looks like that Qt 5.5 freetype font rendering update is the source of the issue: https://bugreports.qt.io/browse/QTBUG-49452
(In reply to Michael Palimaka (kensington) from comment #5) > Do you happen to have media-libs/freetype[infinality] as someone suggested > on the bug? Yes! I have infinality-ulitmate-meta installed and thus also media-libs/freetype[infinality]. However, there is no need to uninstall infinality in order to get get rid of that bug. I've simply: eselect infinality set 3 (linux) and eselect lcdfilter set 10 (linux) in order to fix the problem temporally. I hope qt can fix this upstream.
Qt 5.6.2 is in tree. Closing then.
