Created attachment 116873 [details] Screenshots of kstars with working and broken horizon display SUMMARY I have defined a local horizon using 'Settings->Artificial Horizon. This works nice in Horizontal mode (AltAz), see kstars_az.jpg in the attached archive. But switching to Equatorial mode (RaDec) the drawn polygon is completely bad, and depending on where I center the view starts tinting the whole star map (kstars_ra1.jpg and kstars_ra2.jpg in the archive; the first one is at the same location as kstars_az.jpg, just pressed 'Space' to switch) EXPECTED RESULT The local horizon should be properly displayed also in RaDec mode (or at least only drawn in AltAz mode) SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed KDE Plasma Version: 5.14.4 KDE Frameworks Version: 5.52.0 Qt Version: 5.11.2
Can you attach your userdb.sqlite file? or export the horizon data from it? I want to reproduce it here and work on it.
The file is located under ~/.local/share/kstars
Created attachment 117038 [details] kstars userdb with horizon definition Sure, here it is. The behavior seems to vary. One time it was just not displaying the horizon data in RA mode at all, sometimes the display was almost correct. But usually it draws wild patterns across the whole sky, changing when I move the view.
This was changed to an updated system in 3.5.4, can you please check?
Ah - mea culpa! Completely forgot about this report. Yes, indeed in the current version (git) this problem no longer occurs. The horizon is drawn correctly(*) in all cases, so this can be closed as fixed :) (*) There's another issue now that AZ points **have** to be monotonic, so no overhangs. But that is already marked 'wontfix' (design choice) by Hy ;^>
