@Jean-Baptiste "This is a usability issue which doesn't impact functionality".
If it were as simple as that then changing the priority should not in itself alter the ability to recreate the bug. The fact that after changing the priority to normal and then back to very high makes the problem disappear completely seems to indicate that there is something much deeper going on.
