[Chimera-users] assistance changing pseudobond appearance

[Elaine Meng]

Definitely sounds like a graphics-driver type of problem.  Maybe it would work with linewidth 2 instead of 3, but I really don’t know.

P.S. Similar problem reported last year...

Either closing the Selection Inspector or clearing the selection causes the series of dashes to disappear.  When I control click on a blank part of the screen the dashed line is not restored.  I can rotate the structure and at certain positions the dashedline  reappears but only a certain specific rotations.

It sounds like a rendering problem on your computer, such as needing to update the graphics driver or install a better graphics driver.  You could try clearing the selection (e.g. Ctrl-click in empty space) and seeing if that makes the line reappear.  If you saved the session you could try restoring it and seeing if your line reappears.  Then if you have to change the line again, just try clearing the selection before closing the Selection Inspector to see if that makes it behave any better.  However, you did not do anything wrong and the problem is not within Chimera… this would just be playing around to try to avoid the mysterious behavior.  I don’t have any definitive answer, not knowing the specific cause, sorry.
