User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:65.0) Gecko/20100101 Firefox/65.0 Steps to reproduce: - Open the performance panel in devtools - Open the configuration menu and check - Enable an item which have a warning triangle next to it - Open the menu again Actual results: The checkbox is rendered on top of the warning triangle. See the attached screenshot. Expected results: The checkbox should appear next to the warning triangle.

Florian, this looks like a perf.html issue, but I don't know if you already know about this bug.

Oh, I have perf.html loaded in that particular screenshot (sorry for the confusion), but the menu is actually part of the Performance-tab in the devtools in the browser. So it is unrelated to perf.html. I can navigate to another page and I still see the issue.

Thanks for filing, Michael! Sole: This is the old performance panel. Setting low priority and available for the community, as experimental features aren't visible until users opt in to experimental profiler features and this seems to be Linux only (verified on OSX and Windows).

This is actually an old bug that's already on file.
