Description Philippe Leblanc 2016-01-14 00:15:36 CET

There seems to be a mouse scrolling glitch when switching between applications in Gnome 3. I've seen this happen with multiple applications, but so far testing shows this bug affects only Gnome native apps. 

Basically, if I am using firefox for example as I am doing right now, and I say I switch to Evolution to check my mail, the minute I try and scroll through my list of emails using the mouse wheel, the window moves instantly all the way to the bottom of the list of emails. And it doesn't matter if I try to scroll up or down. It consistently moves the viewing window all the way to the bottom. After that I can scroll up and down as expected, but this bug will happen again if I switch to a different program and come back to Evolution.

And I think this problem specifically happens with Gnome apps as I've seen it occur also in gnome-terminal and epiphany for example. But Firefox and Libreoffice don't exhibit the bug. I'm not sure which RPM this would be tied to and I hope someone else can reproduce the bug, but it can be quite annoying

Does it happen, too, after logging in with a new user?

If so, if you start (as root) 
  journalctl -f

and then reproduce this issue, do you see any related errors/messages?

Comment 2 Philippe Leblanc 2016-01-15 19:31:09 CET

Well now I feel really dumb. I created a fresh user as you suggested, and logged in with it. I ended up not being able to reproduce the bug. I logged back in under my original user and did a little testing and couldn't reproduce the bug either. So at this point it might have been some random small glitch with gnome. If you don't mind, I'd like to keep this bug open for a few more days just in case I notice it to start happening again. This could be a bug that manifests itself after a session has been active for a while. I'll close the bug if it doesn't happen again in the next few days.

Comment 3 Marja Van Waes 2016-01-15 20:35:10 CET

don't worry, Philippe, i'm sure we've all reported one or more weird issues that couldn't (easily) be reproduced.

i'll set this report to unconfirmed for now until it is reproduced or until you close it

Status: NEW => UNCONFIRMED
Ever confirmed: 1 => 0

As I suspected, the scrolling wonkyness has started to appear with an hour or two of usage. I've had journalctl running in the background, but I didn't notice anything bizarre with scrolling. Here's the output for the last hour or so.

I suspect there is a bug in Gnome with some variable that is changed to a value it shouldn't be. And it is being incremented over time. As of right now, the window doesn't move all the way to bottom as it did when I first reported the bug, however, it is suddenly moving downward hundreds of lines when I move the mouse wheel one "tick" mark.

Assigning to the Gnome maintainers, they'll understand the output (I don't).

Btw, is this bug still valid, Philippe?

It's 1½ years later, and there's still no reply.

Assuming this issue got fixed.
