[Bug 1726279] Re: Stellarium performance regression (visibly stuttering)
I've now changed hardware and software. Using Ubuntu 18.10 (development) with stellarium 0.18.0-1 I can't reproduce any bug. ** Tags added: artful ** Bug watch removed: Red Hat Bugzilla #1227295 https://bugzilla.redhat.com/show_bug.cgi?id=1227295 ** Changed in: stellarium Status: Incomplete => Fix Released ** Changed in: stellarium (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726279 Title: Stellarium performance regression (visibly stuttering) To manage notifications about this bug go to: https://bugs.launchpad.net/stellarium/+bug/1726279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Some Linux systems have Qt logging largely disabled. A bit of googling around brought me to sites like https://bugzilla.redhat.com/show_bug.cgi?id=1227295 from which I wrote a summary https://github.com/Stellarium/stellarium/wiki/FAQ#Logfile_has_no_details Maybe this helps. ** Bug watch added: Red Hat Bugzilla #1227295 https://bugzilla.redhat.com/show_bug.cgi?id=1227295 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726279 Title: Stellarium performance regression (visibly stuttering) To manage notifications about this bug go to: https://bugs.launchpad.net/stellarium/+bug/1726279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1726279] Re: Stellarium performance regression (visibly stuttering)
I don't get any of that information. Even tried "--dump-opengl-details" and get nothing other than what's shown in comment #6. Just tried env LIBGL_SHOW_FPS=1 though, and it agrees with Stellarium and prints "FPS = 60.0". But what I see on screen is not 60Hz. It's stuttery like 30Hz/20Hz/15Hz. So it sounds like either: (a) A lower level compositing problem (but why is it consistent between shells and Xorg/Wayland?); or (b) Stellarium really is flipping 60 frames per second but they're not actually unique frames. I'll debug this myself some time, when I have time. Unless anyone can make some suggestions. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726279 Title: Stellarium performance regression (visibly stuttering) To manage notifications about this bug go to: https://bugs.launchpad.net/stellarium/+bug/1726279/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well, I've been doing GL development on these machines [1] for a few years. I know what they're capable of and that 60Hz should appear smooth and not stuttering. Not to mention the identical machine next to it running Stellarium 0.14 is perfectly smooth still... Which log files exactly would you like?

It's quite likely not that bug. However, "Xeon" means almost nothing. Like "Pentium", it can also be 10 years old.
