Bug report #13735
CRS transformation broken in Master?
|Affected QGIS version:||master||Regression?:||No|
|Operating System:||x86_64 GNU/Linux||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:|
|Crashes QGIS or corrupts data:||No||Copied to github as #:||21762|
Projects with Geotif layers being "on-the fly" transformed, which worked fine a few days ago, now generate 100% CPU usage and take many many minutes to be initially read in.
Sorry this is a very generic bug report, but Master is currently unusable with any of my projects that include transformed (EPSG:3762) Natural Earth geotif rasters.
Running up to date Debian testing with GDAL at 1.11.3+dfsg-2

I am not competent to comment on the technical details of the fix for #13665, however the following anecdotal evidence suggests that this is the source of the problem:
1. the time scale is about right - I started seeing this problem last week
2. when things were working I can confirm the presence of "white regions around the pole", but this was not a problem for me at that time.
Here is a test case to show the problem:
1. get http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/raster/NE1_LR_LC_SR_W_DR.zip
2. add layer NE1_LR_LC_SR_W_DR.tif and zoom in on 54'S 38'W
3. apply EPSG:3762
