@EricJRW, try right-click in the top area of the browser window eg in the blank space alongside the tab(s) and ‘+’. On that right-click menu, you may have the option to enable “Menu Bar”, which contains the ‘traditional’ menu items File,Edit,View,History,Bookmarks,Tools,Help.
Normally this /dirty trick does little as slow updates are more usually the re-render process getting behind on one or more of the a. b. or c. tile servers, so the tiles are already marked and in a backlog queue. In conjunction with the corresponding browser caches this means there are 6 sources each tile (at each zoom) can come from, which can result in the patchy and or apparently backwards updating sometimes experienced. Only times I’ve used it normally are to encourage an update of an (normally infrequent) zoom 13 tile eg if a big road has been opened or a large construction site added or similar.
Just want to add that I am also experiencing the same problems, and have been for a few weeks now.
This is a major problem, as I cannot “check” my edits to make sure everything is alright, and has prevented me from being able to do any editing beyond very small things.
Is a good one for tile dirtying. To dirty tiles click the + and turn off the two overlay layers,
then simply right click, and open image in new tab then add /dirty to the url (and /status to view the status).
The manual dirtying has not been working for me given that the server seems to be behind on rendering.
(Note also: there used to be a greasemonkey script for Firefox (which stopped working after a Firefox update), there might be something similar somewhere for tile dirtying).
Is there not a non-OSM-hosted server anywhere (perhaps more local to you) that doesn’t have dozens of taxi apps trying to freeload off it as well (as the tiles at osm.org have)? The tiles at openstreetmap.de are usually a good bet. Also what about the other layers at osm.org - I know that the two Thunderforest layers don’t update instantaneously, but what about the other two?
