Hello all,

I ran into the following issue twice today: I was doing a VFR flight and I used ALT+ENTER to switch to another tab (Volanta in this case, but I'm sure thats irrelevant). When I did that, my coursor disappeared, my screen turned black and the message on the picture popped up. I did a testflight afterwards, and the same thing happened after using ALT+ENTER a few times.

 

Interestingly, I did use ALT+ENTER during both flights before the crash occured and they didn't cause issues. After the second crash, I tried to recreate it, but couldn't. Even spamming ALT+ENTER didn't cause the crash again, so it seems it happens occasionally and its hard to reproduce. Now, I always flew in fullscreen mode and I've always used ALT+ENTER to switch between tasks (never ALT+TAB) but didn't encounter this issue before. I did have DXGI errors but those were resolved and didn't happen when I pressed ALT+ENTER.

I'm using P3Dv5.3.
Any help would be appreciated,
Csanád

ALT Enter changes fullscreen to less than and vice versa, for me.

@AzureFire, this pinned topic might help.

Strange as I am now getting this same error, but when switching to the ifly load manager and not volanta.  Happened three consecutive times to me yesterday and has never happened before then.

 

are you on windows 11 by any chance?  Wondering if that has anything to do with it.

Interesting... I'm on Windows 10 still, so probably not that. Could it be the GPU driver? I have an RTX 3060, driver version 566.36. Since the second time it crashed, I couldn't reproduce it. Did a couple more test flights, flying around and occasionally pressing ALT+ENTER, nothing. Did a proper flight, nothing. Weird.

Not sure which driver I have because I’m not in front of my computer, but i am also on a 3060.  Will try to find time to investigate this more tomorrow. 

Okay, it might be a driver issue then. I'm gonna do some more testing in the meantime...

 

Alright I did some test flights and encountered the DXGI_ERROR_DEVICE_HUNG in this case, when switching to VC view in P3D. Something is up with this driver. I'm gonna roll back to a previous driver and I wrote a bug report to Nvidia. Did you do some testing @okupton ?

Did some brief testing this morning.  Same plane, airport, time of day, etc that I had the crash happen before.  I was not able to recreate the crash.  Will try to complete a flight later today to see how it goes. 
 

really strange…

So it only happens occasionally for you too. Did you check the driver version by any chance? Just so we can see if we have the same driver too?

I’m on the latest driver.  566.16 I think it is.  I updated earlier this week when I was getting the crashes thinking the driver I had installed previously was causing it.

For the RTX 3060, the latest is 566.36. So you had the crashes before you updated the driver and you had them afterwards?

Correct.  I had crashes before and after I updated to 566.36.

Okay, then it might not be driver specific. I'm gonna test more. Until then, lets hope the next driver will fix the issue. 566.36 came out on the 5th of December so the next one should come soon.
What plane and airport did you try it on?

ifly max, FB KSFO.
