What causes an issue with desktop elements losing focus when I move my mouse cursor on the left and top...

I'm trying to investigate this issue for some time now. I'm using Xubuntu and I've noticed that Whisker Menu icon is blinking when I move my mouse cursor on the left and top screen edges, but it behaves normally when I drag it on the bottom and right edges. Not only panel plugins/elements are affected by this, but also other applications, for example Plank.



You can see the issue on this video: https://youtu.be/YXmFXFV_ONQ



Issue occurs on Ubuntu 18.04 (GNOME), Xubuntu, Ubuntu MATE and some other distributions like Manjaro Xfce. EDIT: Kubuntu is also affected.



More details (and videos showing this issue) are here: https://forum.xfce.org/viewtopic.php?pid=48257



Please help me to kill that nasty bug, it's been on my system for a year now, I've noticed it on Xubuntu 17.04. I don't know where exactly to submit this bug, I previously submitted it wrongly on the Xfce's Bugzilla, but this issue is not Xfce specific, now I know that.



Here are some other videos showing this issue:

Kubuntu - https://streamable.com/dyqur
Xubuntu - https://youtu.be/UY4ZuxsPifw?t=15s

OK, there's a workaround for this issue. This bug report tells a lot more about it - https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1795135



I put export GDK_CORE_DEVICE_EVENTS=1 to /etc/X11/Xsession.d/56xubuntu-session and my Xfce panel items aren't blinking any more, and that works with Plank too. Tested on Xubuntu 18.04.

            Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

            Image
            up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title.
