Istvan,

There is a problem somewhere in how libinput in working with kwin and Gtk
apps in Tumbleweed right now. I can confirm the behavior. It also shows up as
a problem trying to use focus-follows-mouse and use the mousewheel to scroll
in Firefox when other windows overlap. (ironically, my touchpad can 2-finger
scroll Firefox just fine when windows overlap -- but that is using the
synaptics driver)

I've opened a Firefox bug with mozilla about the behavior:

https://bugzilla.mozilla.org/show_bug.cgi?id=1907708

but since I've notice oddities in general using Gtk4 apps in how my mouse
using the libinput driver interacts with the application.

In several TW bugs, Yasuhiko has found libraries that need to have the
compile string adjusted to for --std=c11/-std=c++11 features. There may be
something similar with the mouse dependencies.

I still need to boot 15.4 back and compare the xinput/libinput configs, etc..

So long and short, we know there is something wrong in the way the mouse in
interacting with Gtk apps in TW and KDE3. There is also some strange behavior
in KDE3 itself (e.g. press Alt+F2 for Run-Command and enter command that
already appears in the Alt+F2 list. The combobox no longer automatically
completes the name and drops the listbox part down so you can highlight the
command you want -- down-arrow still works)

None of this happens in 15.4. If this is happening in 15.5, then at least
that narrows down the time the change occurred.

Post any other info you have hear about the problem. When I have enough to
know where the problem is, we can write a bug report for it.

David, thank you for your answer.__
I think what you write about  is another issue not the one I mentioned.__
 -- The mouse problem I reported occurs in < 15.4 Leap. I tried Leap 15.1, 15.3, and 15.5. All 3 versions present this behavior.__
-- For me scrolling with the mouse in an unfocused window  works normal.__
The problem was that my mouse cursor theme was/is set to "no theme", that is to default x11 legacy cursor theme (named "the old classic X cursors" in kde3 control center), and recent firefox does not support it. A gtk cursor theme, like Adwaita works normal.__
There is also an about:config setting which if set to true enables old x11 cursor themes in firefox:__
widget.gtk.legacy-cursors.enabled __
I don't really understand why this is not set to true by default, and why a default x11 cursor theme might not supported.__
For now I consider my question to be solved.__
Best regards,__
Istvan
