I'm experiencing a bug with the setting at system settings > window behavior > window actions > mouse wheel > activate, raise and scroll.

While that setting is active, the focused window can permanently ignore the mouse wheel if I interact with the panel or while a popup is active.

For example, if Firefox has focus and I use the mouse wheel on the volume icon to adjust volume, Firefox will permanently ignore the mouse wheel. This can temporarily be fixed by setting the focus to another window, then back to Firefox. This seems to only happen with GTK programs.

Another example is if I get an email notification from Thunderbird, or a file transfer notification, the mouse wheel will be ignored until it goes away.

Let me know what I can do to help.

Also, I have several bugs to report. Should I put each one in their own thread or just put them all in one? I'll do whatever the standard is here.

EDIT: For anybody from the future who's trying to find a solution to this problem; here's how I solved it.

Create the file:

Code: Select all

~/.config/plasma-workspace/env/gtk3_scrolling.sh

Then copy paste the following into it:

Code: Select all

#!/bin/bash
if [ -z "${GDK_CORE_DEVICE_EVENTS}" ]; then
    GDK_CORE_DEVICE_EVENTS=1
    export GDK_CORE_DEVICE_EVENTS
fi

Save the file.
Log out then back in.

The issue should now be resolved, as this is the point where it was resolved for me. If you're still having problems, try a full reboot. If it's still not working, try copying the file to:

Code: Select all

/etc/xdg/plasma-workspace/env/gtk3_scrolling.sh

Then reboot again.

If that doesn't work, then sorry, that's about the best I can do for you. But that's WOMM for ya.
