Bug ID: 368006
Summary: Download progress halts with OSM
Product: marble
Version: 1.14 (KDE Applications 16.04)
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: data
Assignee: marble-b...@kde.org
Reporter: lrajchel1...@gmail.com
When browsing maps with OSM, everything works fine for a few seconds. After
that it becomes virtually impossible as the download speed goes almost to zero,
i.e. the download progress bar stops at, say, 10%, and hardly moves any
further. This happens usually when zooming a location, and then stays like
that, the maps becomes un-browsable.
It's not a simple connection problem - in the meantime the OSM WWW service
works fine and fast. It seems to be related only to OSM, whereas other maps'
data download fast, even those based on OSM, like the OpenTopoMap (OTM): if I
switch to OTP, first the download speed is zero again, but when I restart
Marble, OTM works fine. When restarted with OSM, the download is OK only for a
very short time.
I tried increasing the RAM cache size (disk is unlimited), and deleting all the
config files (from ~/.config and ~/.local) - to no avail.
When run through strace, there are several problems, I'm not sure if they are
related to the OSM issue:

Reproducible: Always
Steps to Reproduce:
1. Browse Maps with OSM
2. Zoom into some location
3. Browse maps a little bit
Actual Results:
The download progress halts and hardly proceeds any further
Expected Results:
Maps' data should be processed almost as fast as when using OSM online service
