Description

I'm using 8b18577. When I zoom out I get a crash. Here is the backtrace:

History

#1 Updated by Giovanni Manghi over 11 years ago

  • Status changed from Open to Feedback

does not happen here, can you attach sample data/project?

#2 Updated by cgsbob - over 11 years ago

I'll try to make my project smaller and put it up somewhere.

Btw, all of the layers are in NAD83 and I was using Openlayer plugin w/ Google Street (so my project is in EPSG:3857). If I get rid of the Openlayer layer and set it to NAD83, QGIS does not crash.

#3 Updated by Nyall Dawson over 11 years ago

Do you see this same behaviour without blend modes? In current master I'm seeing segfaults when zooming and panning certain rasters without any blending applied.

#4 Updated by cgsbob - over 11 years ago

  • Subject changed from Zoom out on rasters that use blendmode multiply causes crash to Zoom out on raster causes segfault.

Hi Nyall. I turned off blend mode and I still have segfaults. So, I've changed the summary of this ticket. I see there has been more work on the raster code, so I'm going to see if updating to master will solve this problem.

#5 Updated by cgsbob - over 11 years ago

  • Status changed from Feedback to Closed

I just updated to 3977cb6 and my project no longer crashes. So, I'm going to close this ticket.
