--- Comment #28 from Chirag Anand <anand.chi...@gmail.com> --- Comment on attachment 122966 --> https://bugs.kde.org/attachment.cgi?id=122966 QDBus KWin support information I can confirm that I have seen similar behaviour with KDE over the past few years and also that, it occurs while my laptop is up for many weeks. The following things happen (I think they are related): 1. Windows stop refreshing or paint selectively. If I am typing text in an input box I won't see until I do alt+tab twice or minimize the window and restore it. I also see strange things like flashing icons. For example, if I click on a menu button on a web page then the icon is supposed to be replaced with another one (highlighting). In this case the previous icon still remains while the new icon appears on top of it, thus, creating some strange effect which is animated (hard for me to even explain). I notice this behaviour mostly on Chromium (probably because Konsole and Chromium is 95% of my work). It occurs on all tabs in that window so I have to close all tabs and then close this window, rest of the Chromium windows remain open and work fine. This happened right now and that is why I wanted to report a bug and came across this bug report. My uptime is *17 days* right now. The only output which I got from journalctl today when this happened: ``` Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: XRandR::setConfig Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Requested screen size is QSize(1920, 1080) Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Needed CRTCs: 1 Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Actions to perform: Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Primary Output: false Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Change Screen Size: false Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Disable outputs: false Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Change outputs: false Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: Enable outputs: false Oct 01 20:10:24 Rise org.kde.KScreen[5383]: kscreen.xrandr: XRandR::setConfig done! ``` 2. I have seen occurrences of blank desktop after logging in. Can't remember if it was SDDM or the earlier KDM. 3. If I connect an external monitor and then disconnect it, I am not able to use my keyboard within the *Present Windows* effect. As if the keyboard input stops getting captured when the effect is on (even Esc key doesn't work). The effect works all fine otherwise but goes haywire only after I disconnect an external monitor. And, this problem doesn't fix itself if I reconnect/disconnect monitors after it has occurred. Attached: QDBus KWin support information.
