Created attachment 201863 [details] Screen recording. Before keying Control-R I began pointing at (not clicking) the scroll bar. F5 works. Control-F5 works. Control-R results in apparent flicker of e.g. the scroll bar but no reload. grahamperrin@momh167-gjp4-8570p:~ % date ; uname -v Sat 9 Feb 2019 08:41:42 GMT FreeBSD 13.0-CURRENT r343883 GENERIC grahamperrin@momh167-gjp4-8570p:~ % pkg query '%o %v %R' firefox www/firefox 65.0_2,1 FreeBSD grahamperrin@momh167-gjp4-8570p:~ % Reproducible with Firefox in safe mode.
Hmm, currently not reproducible with r343308.
Created attachment 201882 [details] Log of update of Firefox (and some other ports) I omitted to note which version of Firefox I used in the (inferior) r343308 boot environment. Today with r343931 I can not make the issue reproducible with either 65.0_1,1 or 65.0_2,1.
Strange … the issue was reproducible with multiple Firefox profiles – one of which was in safe mode – when I first reported with 65.0_2,1. No longer reproducible with 65.0_2,1.
Symptoms have recurred but they're not specific to Firefox. Without reopening this bug, just using this comment as a small dumping ground whilst things are fresh in my mind … Waterfox 56.2.7.1 bugged at e.g. <https://www.reddit.com/r/firefox/comments/aouzd7/is_there_a_way_to_remove_the_current_tab_name/> – so I launched Firefox and found it similarly bugged at the same URL. Mozilla/Gecko only? No. I launched Chromium, similarly bugged at the same URL. grahamperrin@momh167-gjp4-8570p:~ % pkg query '%o %v %R' chromium www/chromium 71.0.3578.98_2 FreeBSD grahamperrin@momh167-gjp4-8570p:~ % Smells like an occasional, transient issue involving the desktop environment or windowing. Operating System: FreeBSD KDE Plasma Version: 5.14.5 Qt Version: 5.12.0 KDE Frameworks Version: 5.54.0 Kernel Version: 13.0-CURRENT OS Type: 64-bit Processors: 4 × ACPI CPU Memory: 15.9 GiB of RAM Compositor settings for desktop effects: XRender, crisp. ---- Probably unrelated, but memorable (extraordinary): half an hour or so ago, whenever I clicked the scroller in the scroll bar of Firefox, the window disappeared. Window regained, after each disappearance, by a simple click on its icon in the (Plasma) task manager. Firefox at the time was probably run with this command: firefox --safe-mode -p test 'https://web.archive.org/web/20190210074311/https://www.reddit.com/r/firefox/comments/aoquet/webextensions_performance_reliability_in_busy/' Transient; not currently reproducible. Also at that time in Surf (maybe browsing the same URL) I had a strange grey opaque overlay at the bottom part of the scroll bar area, behind which the scroller could be slid. Transient; not currently reproducible. ---- Enough dumping. It's not a Firefox bug.
