There is sometimes an issue on the dashboards.
Some tests fails randomly because they are “zoomed-in”. I tried to fix that by making sure “Reset Camera” is called before the screenshots, but it looks like it is noneffective in fixing this issue.
The problem is that, this issue appears quite a lot, and if more than 15 tests fails, they are not rerun and all these failures appears as true positive in the dashboard.
An example can be seen here : https://open.cdash.org/viewTest.php?onlyfailed&buildid=6303178
So if anyone has an idea of what is going on with these “zoomed-in” tests that would be great.
In the meantime I would suggest increasing the number of tests treshold needed to disable the rerun.
