Aven 1.1.15 display redraws slowly on every mouse movement.

[Duncan Collis]

The display of the cave, scalebar, depth indicator, etc, is redrawn slowly (total time is only a fraction of a second, but it's slow enough to see the labels on the depth bar being written in order from bottom to top, for example) whenever the mouse is moved or when the survey is rotated or moved using the keyboard. This makes Aven extremely difficult to use and makes smooth rotation of the cave impossible.

I reverted to 1.1.13 - still the same problem. I think that upgrading from Ubuntu 10.4 to 10.10 may have broken something, although Aven is the only application I've noticed not working properly. Additionally, if Aven is run from the command line, the following error is produced:

The program 'aven' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch? (invalid parameter attributes)'.

The reason this is slow is that your 3D rendering is happening in software ("Software Rasterizer" on line 6 of the info you pasted).

Nothing has changed in Aven in regard to this, so it's probably the video card drivers. You probably wouldn't notice unless applications are using 3D.

You can check what graphics hardware you have with:

sudo lshw|more

Aven should really avoid pointlessly redrawing on a non-dragging mouse move though (unless the mouse moves over a station and the measuring line needs to be drawn/undrawn, and even then we should be able to avoid redrawing the whole scene, and just draw the line on top of the existing image, after saving a copy of what is underneath.
