Visual glitch in treeviews (e.g. "Add Component") under gtk3

[John Beard]

On the current master, I see a visual glitch in the treeview for the add component dialog.

When you enter a search, it looks like something is not quite in sync, as the contents change when hovered over with the mouse or the highlight is moved with the arrow keys.

See the video for a clearer idea!

Could be GTK+3 thing (?)

[Nick Østergaard (nickoe)]

I see the same, at least with gkt3.

[John Beard (john-j-beard)]

I also see this in the treeview on the side the library editor.

[Jeff Young (jeyjey)]

GTK-specific? (Doesn't reproduce on OSX.)

[Maciej Suminski (orsonmmz)]

Funny, I do not see it even with GTK3. WM specific?

My WM is i3 (on Arch). I still see this issue on 4013f6424.

[Seth Hillbrand (sethh)]

This does not happen for me on GTK3. I use xfce for a window manager. Is it i3-specific?

[Seth Hillbrand (sethh)]

If someone with i3 would like to take this on for v5.1, please update the status

[Seth Hillbrand (sethh)]

While annoying, it doesn't prevent proper use. If someone has a thought for a quick fix for this issue, please re-set. Otherwise, we should address in v6

[John Beard (john-j-beard)]

I don't really know what's going on here, but I'm not very familiar with the widget. But here is what I have found it does:

* Open footprint picker (O)
* Type "r" into the filter. You should see some footprints in the list.
** The first few are from the first library with suitable parts (Connector_RJ, 5 items).
** The "Connector_RJ" header is not shown (it's one row above the top)
** The next lib, "Crystal", how an expanded arrow, is expanded, and fills the rest of the list
** At this point, everything is normal
*Type a "j".
** The RJ items remain (expected)
** The "Crystal" items are filtered away and now we have some "Jumpers"
** The "Jumper" heading doesn't have an arrow
** When you mouse over an item, they turn into the item above (so the top RJ12 FP becomes the "Connector_RJ" heading, etc
** Moused over headings that appear do have arrows, but everything is off by one
* Pres "up", the list "scrolls", the top item changes to "Connector_RJ" and everything else falls into line.
* After this, further typing works normally
* Erasing all text resets and you can cause it again

This leads to the workaround: press "up" to sync the list before you press "down" or mouse around.

[Frank Severinsen (shack)]

It seems to be consistent when the treeview contains both libraries and symbols. If only libraries or symbols are present, is doesnt do the update-thingy when it's hovered over

[Frank Severinsen (shack)]

This is also happening in the treeview in the symbol editor.
Something possibly interesting I noticed is the scrollbar scrolls down when as I'm typing.
If I hover over the list (while is has scrolled itself down) it will create the list from beginning at that scroll position. If I scrolls up and hover it will do the same thing again.
I have attached a video to show this behavior (In case I don't makes sense at all)
Please note the Key/mouse monitor in the top.

Is there any info I can provide to help solve this bug?
It's super annoying since I often clicks the wrong things, since it updates when I hover it.

The bug also happens in the *released* 5.1; at least on Ubuntu 18.04 running Unity desktop. It also happens in pcbnew when doing Place → Footprint and typing something to narrow-down the list of footprints:

[John Beard (john-j-beard)]

This might be an upstream GTK+ bug:

* https://bugzilla.gnome.org/show_bug.cgi?id=721597

And I *think* it might be related to:

* https://gitlab.gnome.org/GNOME/gtk/issues/1212

[Wayne Stambaugh (stambaughw)]

If John's assessment is correct, we cannot fix this until gtk fixes it upstream.

+1 here, also added a little recording as GIF, which might be easier to watch.

Thanks for the fix!

I should have said "duplicate bug 1815507". Regardless, the fix is good, and thanks for making it.

@John
This does indeed looks fixed to me
Hats off to you, this is really great!
