Points spontaneously become hidden
I've had a hard-to-duplicate problem for several months; my most recent mention was here: https://forum.locusmap.eu/index.php?topic=7496.msg64786#msg64786
Consistently, but unpredictably, most or all of the points in a folder become hidden. It never happens when I'm "doing something", checking the folder before and after (including after sync); it always seems to happen after some inactivity. SIGNIFICANT: the number of points left visible in a folder, eg 7 / 3000, seems to correspond to the number of points within the screen viewport at the time.
This happens to folders of geocaches that I routinely import on one device and let sync to another, and to my Favorites folder where I frequently edit points and let them sync. I never manually set my Favorites folder to show-none, but do frequently have to set it back to show-all. My sync setting is: show new points: yes.
I have a hunch the screen-viewport observation may help solve this. Thank you.
