SUMMARY It's not possible to "click" on the "Connect" / "Disconnect" button in the NetworkManager applet with a stylus (of a Graphic Tablet). In my specific case it's a "Wacom Intuos PT S Pen"-stylus. The click seems go through the button and hit the "row", making it collapse. I uploaded a video to YouTube showing this bug. https://youtu.be/Yv4cr7Tfd1s I think this bug was introduced with the 5.19.0 release, but it could be ealier but not earlier than the 5.18.0 release. Note; This issue is not specific to the NetworkManager applet but also applies to Bluetooth applet "Connect" / "Disconnect" button. STEPS TO REPRODUCE 1. Use a stylus to open NetworkManager applet 2. Use a stylus to select a Network 3. Use a stylus to click the "Connect"-button OBSERVED RESULT The click misses the button and makes the row colapse. EXPECTED RESULT The button is clicked and the row is not colapsed.

Can confirm with my stylus and touchscreen too. It's a problem in ExpandableListItem.
*** Bug 428914 has been marked as a duplicate of this bug. ***
This is working for me now with gestures turned off in the Wacom KCM (which is the new default, because if breaks touch events in Qt software)--with the caveat that the hit area is offset on X11 with 200% scale; I have to position the stylus twice as high as I would ordinarily need to. Let's see if that happens on Wayland too...
OK, on Wayland where the coordinates are mapped properly, I still cannot click it. Other ToolButtons are clickable, so it does seem to be an issue with just this component.
