Footprint Editor filter does not update the list properly

[Leandro Heck]

The filter kind of works but when I pass the mouse over the filtered results, the list updates. I think all items are being replaced by its next item or something similar.

Can't reproduce, can you please provide a description of what exactly is wrong and steps to recreate it? A screen recording would also be helpful.

[Leandro Heck (leoheck)]

For some reason I could not record the screen yet.
But to reproduce:

- Launch the Footprint Editor
- Go to the libraries search and type something like "ba" for banana connectors
- Pass the mouse over the list with the results (the list should be bigger than the screen I guess)

So, the items will change its position as soon mouse passes over them.

I was testing...
If you type only "b" it does not show the issue.
If you type "ba" it will reproduce the issue.
The same with "c" and "ca".

Maybe it generates the problem after adding a second character because it is not necessary to hit enter to search for results.

Michael, here is the video.
The cursor is not visible, but my mouse is making the list items to change.

Thanks. Does this happen with any other tree controls (e.g. Symbol Editor, Choose Symbol dialog)?

[John Beard (john-j-beard)]

This is an issue in all tree views and (I theorise) is a GTK+3 issue.

Damn I searched for this duplicate for ages. Thanks John!
