lximage-qt drawings not always visible

[Chris Guiver]

-- background

this initiated with https://askubuntu.com/questions/1148764/lubuntu-19-04-why-dont-drawing-tools-work-in-lximage-qt
I was able on installed 19.10 & 19.04 systems, plus today's 19.10 daily ISO to make drawings appear & disappear on screen.

-- to recreate

1: hit printscreen to save image
2: i select whole screen
3: image-viewer (lximage-qt) opens, I maximize to use a whole screen
4: draw an arrow over part of display (you won't see it drawn)
5: switch to 'fit' (view fit or icon) and the arrow drawn will show
6: if you switch back to original size; drawings made will disappear, however re-appear if you fit-to-window

I've re-created this on Lubuntu 19.04 & my installed 19.10 system, plus today's daily ISO (qa-test)

Of note: I was able to re-create it using debian-testing & opensuse-tumbleweed, so I believe it's an upstream (LXQt) bug.

Status changed to 'Confirmed' because the bug affects multiple users.

I was able to re-create this using today's focal ISO (2020-01-15)

The only difference was as PRTSCR is now handled by `screengrab`, I selected "Edit In.." and selected `lximage`.

Calling this low because the annotations *are* present, despite the weirdness in display. You can save the file and they'll be there. Also, re: weirdness, my initial arrow showed fine. It only disappeared when going original size.

I don't think further testing on this is needed until the upstream bug is resolved. On that subject, it seems the opinion is that annotations were an accidential feature ("lximage-qt is an image viewer, not an image editor") and the plan is to hide them by default with hope that maybe someday they might get fixed (which is to say they probably won't very quickly). So I changed my mind: wishlist.

Just got an email upstream

tsujan commented Fixed in lxqt/lximage-qt@e6e0fc9

NOTE: The commit had some problems that were fixed by other commits later, in the git. upstream bug has been closed.
