Title:
  Yellow/Black Checkered Flag while Object Picture is Loading

Status in Stellarium:
  New

Bug description:
  Compaq Presario V2335US
  Win XP Pro SP3
  1.85Ghz Intel Pentium M CPU, 1G Ram
  Mobile/Intel 915GM/GMS, 910GML Video
  Latest Video Drivers Installed

  Atleast since v12 RC1, RC3 and final v12 when starting the Stellarium
  program I can see several square patches that are actually
  yellow/black checker boards where object picture files should be
  (Moon, M42 etc..). These picture files seem to load much slower then
  in previous versions and can be visible for up to 7 seconds. This
  problem is even worse when using the ocular plugin as the entire
  circular view of the ocular is a yellow/black checkerboard. Have tried
  at a clean install, running in opengl-1 and opengl-2 and problem still
  exists. It is not that it does not work as in previous versions the
  object pictures took a few seconds to load as well but there was not
  the checker flag washing out everything else. It eventually loads the
  object picture and goes away but this is certainly not a step forward.

As fact this two reports - this and #1114645 - describe one problem - not enough memory for textures loading. We can hide visual effect for this issue but we can't solve root of problem - size of videomemory.

This worked fine in 11.4, same computer. It did take a few seconds for the object to appear but during the loading there was no Yellow/Black checkerboard. If there is a way to stop/block the checkerboard that would be Ok. I tested this on an other computer using ATI AGP video card with 512M onboard video memory and it also does this but only for a spit second. The laptop displays the checkerboard for up to 7 seconds.

Robert

Hmm... This is odd. Can you give log.txt from other computer (which using ATI AGP)?

Sure Thing - Here Ya Go. I would send a screen shot but its only there or a split second and I am not that fast LOL!

Robert

Here is another screenshot of this problem from the Laptop, It shows that this is happening to all the object pictures, not just one of them, during normal mode not using any plugins. This is after doing a clean install and having first deleted the old config file and starting with a clean, new install. These patches/checkerboards are visible for up to 7 seconds on the laptop. On the Desktop with ATI 512M AGP card they appear but vanish within a split second but they do appear. Hope this may help. V11.4 did not have this problem.

By default placeholder are disabled but it's can be enabled for debugging since revision 5842:

Not so sure this is fixed, I no longer see the yellow/black checkerboard but while the background image is still loading I do see some sort of nebula cloud. It is the same nebula cloud that displays regardless of object I am looking at. This would be much better to display nothing untill the actual background loads.

I think you need press I to disable all textures for nebulae.
