Confirmed on Oseo4W 64 bit - thanks Totò

It may be GDAL's problem, with 2.2.3 this does not happens. If confirmed this should be closed as upstream.

#3 Updated by Paolo Cavallini about 5 years ago

  • Status changed from Feedback to Open

It is confirmed on two os. Unclear how to check it can be solved upstream.

the evidence (test on two different OSes with QGIS 3 and GDAL 2.2.4, works ok) suggest that there was a regression upstream, therefore this would probably need to be closed as "upstream".

It could as well be a problem in QGIS. No way to tell without an analysis.
