With 12.6 the map tile where tour is located are drawn with black background, which makes this version quite useless. I am running the 64-bit linux version on Ubuntu 12.04 LTS.
I tested it with Ubuntu 10.10 and it worked, but now I will do tests with Ubuntu 12.04
you can set the tour painting method in the preferences: http://mytourbook.sourceforge.net/mytourbook/index.php/documentation/preferences/appearance-map#tour-painting-method
can you test the other method
I discovered that the basic method creates black tiles but the enhanced method paints the tour correctly
I can confirm the problem with Linux Mint 13 64-Bit. The enhanced method for tile painting does work flawless.
Thank you Wolfgang for the software!
Take care that you have installed the 32-Bit Java-VM (otherwise MyTourbook will not start-up).
The enhanced method works perfectly. The vmargs needed to be set to avoid crash at higher zoom levels.
I have tried to add the vmargs options like:
./mytourbook -vmargs -Xms128m -Xmx768m
but I still get a lot of crashes while zoom in/out with the following error message:
mytourbook: /build/buildd/cairo-1.10.2/src/cairo-surface.c:614: cairo_surface_reference: Assertion `((*&(&surface->ref_count)->ref_count) > 0)' failed.
This seems to be another issued (multi-threading problem) - and occurs when
calling set_source_surface on an invalid surface. (http://comments.gmane.org/gmane.comp.lib.cairo/18320)
Wolfgang - could you please check this? Let me know if you need further traces etc.
I fixed the problem for the basic painting method, available in the next version (will be released in a few weeks)
I will not fix issues which are deep in the cairo library, I have no skills to solve it at this location
thank you for the bug fix. Version 12.6.1. is working perfect!
