I’ve been experiencing rendering issues in the WME over the last two days. It manifests as roads not fully showing and cutting off at random points. Scrolling does sort of fix it but only temporarily. I’ve tried it on Edge, Chrome and Opera and it’s there on them all.
Anyone else finding this as they edit?
Yes, the roads layer isn’t loading properly. I’m seeing (or not!) this too. Reloading doesn’t always fix it, sometimes have to reload it a few times. I’m using Chrome myself
This is a global issue that looks to be affecting the ROW WME servers. There’s not a lot of point reporting it in a local country forum. 
It’s been reported in the global WME forum and staff were sent an SOS message a little over an hour ago.
