Bug report #19714
raster layer causing hangups for long periods with opacity slider widget
|Affected QGIS version:||3.2.2||Regression?:||No|
|Operating System:||Windows 10||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||no timely feedback|

Often, but not always the system hangs locking the GUI. This can last a minute or more. It may happen in other situations, but I can verify that a raster file I created from IDM interpolation will cause this condition. The file size of the raster is about 750k. The system is more stable when opacity slider is removed.
Whether the opacity slider is on or off, I notice that my I7 two physical core/4 logical core PC shows all 4 cores heavy processing during this period of unresponsiveness no matter whether I set rendering to 4 cores, or many cores, or turn off multi-core rendering altogether. This symptom also exhibits itself in 3.0 installation, but seems worse in 3.2.2
