Bug report #13569
memory leak in renderer
|Affected QGIS version:||master||Regression?:||No|
|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||21611|
When triggering redraws, especially on big projects, memory slowly or rapidly increases. High memory usages leads sometimes to crash.
Issue dicussed and confirmed here: [[http://osgeo-org.1560.x6.nabble.com/Possible-memory-leak-in-QGIS-redraws-td5228794.html]]
noplugin option does not help. It has been present at least since 2.4. 2.6 is severely touched, when 2.8 is better. 2.10 and master stil affected
We need to narrow that issue down since it is a real blocker for long sessions and big project.

Are you able to share some more details which may help? Specifically:
- what renderers & symbol styles are active in your project?
- does disabling all labeling help?
I've been unable to track any leaks within QGIS but also see this memory usage increase. My current hunch is that the leak is either within Qt or the geos library (they are the only possibly relevant leaks reported under valgrind).

suggest that this has been fixed and what is not it will be with the switch to qt5. Please reopen of necessary.
