tests fails on linux

child accessible [ 'col2' , role: columnheader] at the point (157, 1) of

Let's move discussion here.

I think the problem is we get wrong x coordinate. We expect to find col1 but we get col2. I don't think the problem in QI.
The worst thing this test works successfully on my and Marco's linux machines.
Btw, on my linux machine x coordinate is 145, on machine where test fails x coordinate is 157. Maybe it's timing problem?
Do you have more data on the coordinates of treecols, col1, col2?
I'm wondering about css padding. Treecols might have a different x y than col1.

In this case we should get treecols accessible but we get col2.
