Refinements...
B1. Ran refresh.sh per last post and opened Image.
B2. Opened playground without adjusting native window.
B3. Three times successfully inspected [A], seeing "2".
B4. Maximised native window
B5. Inspecting [A] caused forked child Image to remain open with error
> FT2Error: Freetype2 primitive failed [error 2][unknown file format]
C1. Ran refresh.sh per last post and opened Image.
C2. Maximised native window.
C3. Opened playground
C4. Inspected [A] once, getting...

C5. Saved&quit Image
C6. Restarted, got...

(Segmentation fault)
D1. Ran refresh.sh per last post and opened Image.
D2. Opened playground
D3. Inspected [A], successfully getting "2"
D4. Several times, Saved Image, Restarted Image, goto D3.
D5. Maximised window.
D6. Inspected [A], forked child Image stayed open, playground is
red-pane-of-death,
predebug window... FT2Error: Freetype2 primitive failed [error
2][unknown file format]
D7. Quit child Image without saving.
D8. In parent, save&quit then restart produces error...

Btw, sometimes the the forked child Image (e.g. named
3635603974497675) that starts up, and sometimes the parent Image is
started, so there are two native windows open titled
"Pharo-5.0-Issue-Tracker-image.image" Both encounter similar frequency
of FT2Error errors.
Trying incrementally changing resolution
244x665 okay = 2
244x683 okay = 2
244x695 okay = 2
244x709 child error FT2Error
244x685 okay = 2 (recovered)
244x700 okay = 2
244x705 parent error Error: External Image Failed: 34304
244x709 okay = 2
244x716 okay = 2
244x918 okay = 2
244x1147 child error FT2Error
The last one is full height. Now I repeatedly inspected [A] with
strange results.
Using CTRL-I would predominately fail with some successes. Most fails
occurred in spawned Image with a FT2Error. Using "Inspect" from the
context menu predominately succeeded, with some failures.
Also, sometimes the spawned image startup is s-l-o-w, so the 'timeout'
inform executes, even though the inspect [A] successfully returns "2".
More mucking around indicates a definite tendency to error more often
when the window is large.
