[Marble-devel] Re: Problem with map creation

[Torsten Rahn]

Hi Helmut,
 
I just removed all my tile data in my home directory and the Marble 
configuration files. 
Then I started Marble from master and 
selected map themes which create tiles on runtime (such as Satellite, 
Temperature, Precipitation, etc.).
Now all of this worked fine (and without a warning on the command line).
Usually the only problem with running stuff in a non-guithread is with 
QPixmaps since they use the non-thread-safe XServer - at least if 
true pixmaps are used (in graphicssystem "native" - since Marble is currently 
using graphicssystem "raster" by default, I switched to "native" but still no 
problems ...  .) 
 
The usage of pixmaps in a non-guithread is usually indicated by a warning on 
the command line (which doesn't occur here). Also I checked the tile creator 
for QPixmaps (but we are just using QImage in there which is threadsafe).

So what am I doing "wrong" ? :-) How can I reproduce your issue?

Best Regards,

Torsten
