Hi,
I have a small issue, but I don't know how to report it correctly.

Short:
For certain ebook, when viewer width is smaller than 964px, viewer hangs (or does something longer than my patience allows) on page 1 of ebook.

Long:
Running Windows 10 64bit eng, latest updates. Calibre 7.17 64bit.
This ebook has titlepage, which displays and then it has page 1 consisting only of svg+image reference of image-1.jpeg. This image seem okay, 530x751 px.

viewer-webengine has
"geometry-of-main_window_geometry": {
"frame_geometry": {
"height": 791,
"width": 965,
"x": 338,
"y": 136
},

and ebook displays normally, i.e. I can start on titlepage and pgdn to chapter 1.

When I change width of the viewer to 962px (by mouse, because it seems that variables above are read-only), ebook displays titlepage and on first pgdn 'hangs'. Nothing reacts, even closing takes 2-3seconds to complete.


How can I report/provide logs etc. to debug this stuff?
