Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Critical / Bugs

White Square / No FBO

The white square is the popup message / tooltip, shown via the Canvas. The texture or framebuffer used for the canvas isn't working. This seems to happen on some very old drivers.[1]


we talked about this issue a (long) while ago - and what would really be interesting is if people seeing this could also try one of the aircraft using other OD_gauge based avionics (navdisplay, agradar, wxradar etc) - because under the hood, this should be using the same OSG code - if those instruments work/display properly, it is likely that this issue can be fixed once and for all by looking at what the Canvas FBO/RTT setup code is doing differently compared to od_gauge based avionics using the same back-end. If I remember correctly, we also once posted patches telling OSG to use a non-FBO fallback - unfortunately nobody seeing this issue was able to follow up to test this. If in doubt, anybody seeing this, PLEASE post a screenshot showing your help/about dialog (and ideally your fgfs.log file): About dialog

Likewise, this should affect any other FBO use-cases in FlightGear, including multi-camera setups (think Rembrandt)[2]
