Wine log: opened lightroom on a 20 megapixel image (Develop module), zoomed in
to 1:1 (image disappears), then panned to the visible lower-left region and
closed lightroom.

In Adobe Lightroom 6.14 and newer (tested on 6.14 and 7.5, while 6.0 works
fine) images partially disappear when zoomed to 1:1 magnification in the
Develop module. In fact the lower-left region does not disappear: after zooming
in a region roughly the size of the previous viewport (about 1920x900 in my
case) remains visible; but the image has in fact become larger, so that it is
mostly invisible.

Kubuntu 16.04.5, Intel graphics.
