Comment 1 Jasem Mutlaq 2019-07-17 06:15:07 UTC

Can you check this behavior occurs in the KStars nightly packages for Ubuntu?

Comment 2 Jasem Mutlaq 2019-08-08 01:01:38 UTC

Please check KStars 3.3.4

Comment 3 James 2019-08-08 10:40:20 UTC

I wasn't getting it in the 3.3.3 release compiled from sources with latest indilib so its likely fixed.  I am just building 3.3.4 and will advise if an issue as well.

Comment 4 Jasem Mutlaq 2019-09-29 14:41:22 UTC

This is fixed in upcoming 3.3.7
