Bug report #16802

Master crashes with 2 WMTS layers and scrollwheel use

Added by Richard Duivenvoorde over 7 years ago. Updated about 7 years ago.

Status:Closed
Priority:High
Assignee:Alessandro Pasotti
Category:Web Services clients/WMS
Affected QGIS version:master Regression?:Yes
Operating System:Debian and Windows Easy fix?:No
Pull Request or Patch supplied:No Resolution:fixed/implemented
Crashes QGIS or corrupts data:Yes Copied to github as #:24701

Description

Tested here on:
- Debian testing fresh compiled of 6t july 2017
- Windows 2.99 osgeo4w64

Both crash when I add 2(!) WMTS raster layers to a project.

Tested with a new config (NO plugins!):

qgis --profiles-path /tmp/qgis

Create a fresh project (EPSG:28992)

Add 2x times (the same or different) rasterlayers, for example via the Python console:

qgis.utils.iface.addRasterLayer(
"tileMatrixSet=EPSG:28992&crs=EPSG:28992&layers=brtachtergrondkaart&styles=&format=image/png&url=http://geodata.nationaalgeoregister.nl/tiles/service/wmts/brtachtergrondkaart", # uri
"wmts master example", # name for layer (as seen in QGIS)
"wms" # dataprovider key
)

Now do some scrolling using a mouse wheel or so (you also create some bookmarks and run around these).

Sometimes after a couple of seconds, sometimes after some more time QGIS just crashes
