Hello everybody,

I'm running the Qgis version 3.4.4, but I had the same problem with 3.4.1, on a Core i5 with Windows 10 system.

When i try to open a .jpg file as a vector or in the georeferencer, all i got is these kind of images (depending on the zoom) you can see below:

I can replicate this issue with QGIS 3.6.0. This was not an issue before QGIS 2.18, and with QGIS 2.14 it still works.
A sample is available on
www.vewa-ev.de/Dokumente/Wijnands/Bilder/sample.zip
and holds a JPG with an MapInfo TAB file holding its georeference. The JPG was not written with MapInfo, but probably for 10 years with XnView.

This is probably a problem with a library, not QGIS itself.

Is this valid with latest master/3.10?
