This is 2 issues, the failed resize and the lack of bigger cursor.
Reopened
#75 Cursor too small on github. geoo filed this, then eventually grew happy with the small cursor, and nobody else wanted it bigger since. It would be nice to scale the cursor independently of the window size or resolution.
When you resize gridded images, you must keep the outside border 1 pixel thin. Lix will detect this border during file load, cut the bitmap according to the frame color, and treat the image as having several frames.
With 2-pixel-thick border, Lix will detect this image as ungridded, and treat it as a single frame. As a result, you will see the entire image instead of the first frame, and error texts instead of all other frames.
