raster looses green band on saving

[RatInTheField]

What is the bug or the crash?

Using tool Clip Raster By Extent, I clipped a raster to a new extent expressed by drawing on the screen. The raster was saved under the correct file name, but only showed red and blue bands. Green was not visible, giving the image a strong magenta cast. The issues can be worked around by setting the Properties for the new raster layer, by setting Green band to 'band 2,Green'.

This issue has been noted, but not yet reported when using the plugin 'Freehand Raster Georeferencer'

Steps to reproduce the issue

1 select Clip To Extent 2 select an input raster 3 select an extent 4 identify an output file 5 Run the task 6 Observe that the new raster layer shows only Red and Blue layers

@RatInTheField, could you please clarify if the issue does occur or doesn't occur using a new QGIS user profile, what is the relation of the issue with the 'Freehand Raster Georeferencer' plugin you mentioned in the report and if with "Clip To Extent" you mean the "Clip raster by extent" GDAL processing algorithm? Could you please provide a sample raster layer and an extent in order to reproduce the issue?

The issue did NOT recur in new profile

what is the relation of the issue with the 'Freehand Raster Georeferencer' plugin you mentioned in the report

Freehand Raster Georeferencer was the first tool that I noticed that triggered the issue

and if with "Clip To Extent" you mean the "Clip raster by extent" GDAL processing algorithm?

Yes

I hope these help, let me know if you need anything else

This means the issue is very likely not actually a QGIS issue, but it may be due to the Freehand Raster Georeferencer plugin or one of the other plugins installed in your user profile. Anyway, I've tried using the "Freehand Raster Georeferencer" 0.8.3 plugin using QGIS 3.28.2 on Windows and the exported georeferenced raster layer is correctly displayed in QGIS with red, green and blue bands. Could you please provide a sample raster layer that doesn't show the green band when imported in QGIS?

It seems to me the info contained in the attached MS Word file don't show any issue with the "Clip raster by extent" GDAL processing algorithm. Could you please clarify this aspect?
