bug#67604: Motion problems with inline images

[JD Smith]

Strange.  Can I ask your (frame-char-width) and (frame-char-height)?  I haven’t 
yet found a font or size where the bug isn’t discoverable.  Usually at multiple 
frame widths.

Just confirming your buffer looks like:

And that *Messages* includes something like:

Checking with red image width 139
Checking with red image width 140
Checking with red image width 141
Checking with red image width 142
Checking with red image width 143
Checking with red image width 144
Checking with red image width 145
Checking with red image width 146
Checking with red image width 147
Checking with red image width 148
Checking with red image width 149
Checking with red image width 150
Checking with red image width 151
Checking with red image width 152
Checking with red image width 153
Found Bug at offset 7 = 153 pixels
