Hi,
QGIS (0.8 SVN 2007.01.01) renders rasters extremely slow at high zoom
levels.
Take for example this raster
https://svn.qgis.org/trac/attachment/ticket/475/10res.tif
It is only 64 cells, but at a zoom level circa 1:60 panning get's
painfully slow. At 1:10 it gets impossible. On a 1,86 MHz ATI X700 laptop.
Can anybody reproduce it? Maybe it is just my setup... If it is not
only me, is the defect in QT or QGIS, and could it be fixed if the latter?
Cheers,
Maciek
