- what OS (Windows Xp/Vista, Mac etc.) are you running?
- what FlightGear version do you use?
- what graphics card do you have?
- does the problem occur with any aircraft, at any airport?
- is there any output printed to the console (black window)?
- copy&paste your commandline (tick the "Show commandline box on the last page of FGRun or the "Others" section on the Mac launcher).
- please upload a screenshot of the problem.

If you experience FlightGear crashes, please report a bug using the issue tracker (can be also used for feature requests).
To run FlightGear on old computers with bad OpenGL support, please take a look at this wiki article. If you are seeing corrupted/broken textures, please see this article.

Missing label menus if /rendering/multi-samples is enabled

I use flightgear 3.4.0, archlinux 64 bits, ati radeon HD 4650 PCie, with open source driver ( radeon ), intel CPU dual core 3.33 Ghz, 4 Gb ram,

kernel 3.19.2, mesa 10.5.2,

I notice that the first item in flightgear menus is missing if I use the property sim "--prop:/sim/rendering/multi-samples=3",

for example you can see thig bug here, the first item ( or label ) is missing on each menu :


this bug occurs only if I use the option "--prop:/sim/rendering/multi-samples=3", If I set to zero ( --prop:/sim/rendering/multi-samples=0 ) then I don't have the bug on the menus,

the command line who triggers the bug :

fgfs --enable-auto-coordination --disable-real-weather-fetch --enable-clouds --enable-clouds3d --bpp=32 --timeofday=noon --prop:/sim/rendering/multi-sample-buffers=true --prop:/sim/rendering/multi-samples=3

I tried to disable ALS, rembrandt but it doesn't solve the bug, the only way to avoid the bug is to use a "zero" value for the option "--prop:/sim/rendering/multi-samples" ( "--prop:/sim/rendering/multi-samples=0" )

That's probably related to your hardware being ATI/AMD-based, and the PUI (legacy GUI) integration with OSG code, and a few incompatible/untested settings (think shaders/effects, rembrandts/als etc) - PUI is fixed-function pipeline code, while most of FG is increasingly being moved to support more modern code using shaders and effects, or at the very least OSG StateSets.

However, there are a number of ongoing efforts to phase out the existing UI scheme and use a new one - the most active efforts currently being "Phi" (by TorstenD) and the Qt5 effort by Zakalawe.

A while ago, Jabberwocky was working on a new Canvas-based menubar - I haven't seen any updates lately, but the progress back then seemed promising, so you may want to get in touch with Jabberwocky to see if he actually finished anything useful that he's willing to share with you:

This is something to do with the builtin bitmapped font and shaders as it affects me when I have either rembrandt or ALS turned on;

If you change the gui current style in either preferences or autosave to 0 it'll use a real font which fixes it mostly (there are still certain elements in the GUI such as MP Pilot list that use the builtin font)

<current-style type="int">0</current-style>
