Autocad objects coloured rgb disappear on mouse over

Hi there,

I if I add an object, let's say a line to the DB.  And colour it with an

RGB (255, 255, 255) value.  When I hold the mouse over the line,

it disappears.  Move the mouse off the line and it re-appears.

 

Any-one know why?

 

Cheers,

 

Martin.

Hi,

 

what happens if you disable SELECTIONPREVIEW?

Hi.

 

can you upload this drawing? And what version of AutoCAD plus what background-color do you use?

I have my BG set to Black.  After your last post I changed it to red to try it out.  And it works as normal.  But I need the background to be black.

 

Ta,

 

Maritn.

Hi,

 

>> After your last post I changed it to red to try it out

Oops, when I open your drawing the line is green (RGB = 87,189,55), do you have a problem with your monitor or gc?

Try this drawing on another workstation, just to verify!

There is no problem with his monitor.

 

This is a bug.

 

When SELECTIONPREVIEW = 1 (dash only), objects with RGB colors disappear completely.

Hi,

I have set my background to black, I draw a line with true-color 255,255,255, I set the SELECTIONPREVIEW to 1 and to dashed-only-mode ==> when I move my mouse over the line it does not disappear.

 

And as the OP stated that he tried also to disable SELECTIONPREVIEW I don't think this is an issue based on that.

Well, I have SP1.1 installed, maybe that's a difference?

After having a closer look, It may not be a bug in AutoCAD, because it only happens here when using hardware-accelerated graphics. When I disable that, the line is drawn correctly. The system I noticed the issue with is using an ATI Radeon consumer graphics card and driver, so that's most-likely where the problem is.

I have just turned hardware accelaration off in options and your right it fixes it.  Not sure how I can leave this off as CAD slows to a crawl.

 

Thanks loads & DOH at the same time!
