rendering glitches
      #446278 - 06/13/06 01:14 AM

I'm thrilled to now have Google earth for Linux. I've installed it on two seperate machines, both of which exhibit rendering artifacts. Here are the details:

Machine 1:
Athlon64X2, 2GB RAM, Ubuntu Dapper (64 bit), Asus A8N-VM CSM motherboard with on-board nVidia graphics.
Symptoms: Transfomations and lines appear correctly. However, textures are mapped incorrectly onto surfaces causing images to be rendered in the wrong place and surfaces without textures (can see "through" the earth to the stars on the other side)

see: http://www.secretlab.ca/google-earth-screenshot-1.png

Machine 2:
Generic DELL box w/ Intel Celeron 2.0GHz, Ubuntu Dapper (32 bit), Intel 82845G onboard graphics controller.
Symptoms: Clipping regions and viewport size appear to be set incorrectly. On startup; earth view window has bottom status bar rendered 1/3 from the top of the region. After resize, the status bar usually settles back down to the bottom of the window, but the viewport clear region does not seem to be set correctly. For each new frame, part of the viewport is cleared correctly, but the rest does not get erased between frames leaving stale pixels from previous frames. Unfortunately, I can't provide a picture for this issue.

I hope this data is useful to the Google Earth team.

Cheers,
g.

I have also a strange problem with the GoogleEarth V4 under Linux.
After playing a bit with the zoom in/zoom out and with the 3D Buildings layer (turn on, turn off) I can get a quite weird picture. It looks as a bad refreshing.

Please check:
strange image

My system is:
AMD Athlon 1 GHz.
256 MByte RAM
nVidia GeForce2 MX 400
Slackware Linux 10.2

Hope this information could help!

Regards,
Dudee

Try starting X with 24 bpp. So this 2 lines in your xorg.conf look like this:

Section "Screen"
DefaultDepth 24

instead of

Section "Screen"
DefaultDepth 16

You may have less fps on 3D-apps with this.
Got a Radeon IGP 320M with drivers from X.org 7.1
With wine picture is fine with 16 bpp.

I can report the problem on Mandriva 2006 with a relatively new Nvidia card. It is appears as though it may be a memory or zoom level issue - I get various zoom levels in some of the tiles - the screen shot above is pretty close. Zooming creates a mind-bending affect.

I check my xorg.conf settings - I'm already at 24 bpp...
