@SoS It's difficult to guess without more info or a sample data set to test on.

Not working in 2.12.3 (Win 8.1) either, maybe this needs a bug report.

comment QGIS Real-Time Vector Layer Creation
@JolyDroneSP It's possible. I did a search here for "qgis refresh canvas python" and got some helpful hits: gis.stackexchange.com/q/18197/1297 gis.stackexchange.com/q/111039/1297 gis.stackexchange.com/q/12319/1297

comment Why does QGIS Browser 2.12.1 keep freezing/crashing when I try to view a csv data table?
I've been having trouble with CSVs lately too with the latest QGIS and GDAL but haven't had time to dig into it. Can you try and reproduce the problem - that leads to some details that a dev can help with and this might be a potential bug report for either GDAL or QGIS.

comment Split SHP file using ogr2ogr
What operating system are you trying this on? It's a trivial script but knowing what system you're trying it on would help you get a targeted answer.

comment Visualize PostGIS 3D line geometry
Does it help if the data is converted to shape using -dim 3 -zfield {field_name}? That would make gdal change the coordinate dimension to 3D.

comment In PostGIS: how to split linestrings into their individual segments?
Can you share maybe a little of what you tried in terms of SQL? That would probably help you find a solution. Have you tried a combination of ST_DumpPoints and ST_Split?

comment after truncating a table in postgres, why does qgis lose track of updates/features?
Sounds like some kind of index or primary key thing. When the table is truncated, does it help to vaccum analyze and reindex it before it starts to be filled again?

comment How to set position of label around a point in qgis according to a field
@lypsyor If you set the quadrant using the "around point" option than you can adjust the "Distance" to something so that it doesn't overlap the symbol. How come you can't set the quadrant for "around point", is the quadrant option not there?

comment Why are the Google basemaps no longer appearing in QGIS?
Changing EPSG:900913 to EPSG:3857 would eliminate the pop-up from QGIS asking what the projection is when the xml is first loaded.
