The issue i have come across in open rails is
When in the cab view of any 59 class loco that all the windows wont stop flashing yellow and red
however this occurs only when in the cab view and doesn't happen from the outside
and this problem does not occur on any other loco's.
any help with this issue would be appreciated as i absolutely love the 59's
I downloaded the oil burner from coalstonewcastle and tested on my pc but did not have any yellow flashing.
I would have a look at the OR options in the 'Video' tab. Try with 'Glass on in-game windows' on and off as well as in Window mode and full screen to see if that makes a difference.
Also check the OpenRailsLog.txt file (normally on the desktop) as that may reveal what the cause is.
Otherwise try using a cabview from another loco. If the problem goes away it is probably your grapics card having an issue with the ACE file in that cab view. Try opening the ace file in TGATool2 or similar and save it back again. This may 'fix' the issue.
Hope this helps.
