For a lot of people it has been happening that long. Personally I’ve been experiencing it for over a year now (just look at when I made this topic). At the time of making this thread I was finding reports of the same issue for over a year before then. So this issue definitely has been happening for a long time.
I’m using fullscreen windowed and it still occurs.
I’m sure it’s an issue with the game engine. Aces of Thunder uses the same engine and I’ve been experiencing the issue in that game too but a lot less frequently.
I specifically have to be in fullscreen (windowed probably will let me do it too but I’m not playing windowed) in order to be able to alt-tab without freezing. Fullscreen windowed causes the freeze. No idea why.
Happens to me on a 4k, happens less than it did on my UWQHD’s but after todays patch its happening a lot again lol
What GPU & drivers are you using?
With RTX 4070 I get pulsating shaders/lighting after a bit being alt-tabbed, but never freezing or crashing.
RTX 3080 and whatever the latest driver version is or has been since I made the report for the issue.
RTX 5060, fully updated drive, keeps freezing when I alt tab with Direct 11 even in the hangar.
So apparently this issue has now been fixed according to this report. After an update in mid September I finally stopped experiencing this issue but only now they claim it’s been fixed today.
Can anyone who has recently been suffering with this issue check and see if it has been fixed for you?
So the original accepted report has already been forgotten. Someone created a new report a month ago. It was accepted at the same time and fixed after a month.
Maybe we should start writing reports in Russian?
It’s what I’m thinking from now on. Any issues just write the report and chuck it through google translate.
Seems to be the best way of getting anything fixed.
My original report got a response within 6 months, but the russian report gets a response in under 2 hours.
There is only one thing that was different in my case. The game would freeze after alt-tabbing several times, but it never recovered or displayed any error message. I simply had to close it via Task Manager.
Not sure when I’ll check it, though. I haven’t been playing much War Thunder recently.
This is what was happening to me and what I said in my report, the game had to be force closed via task manager.
(re-typing, accidentally deleted the first post)
Hello! I am a developer on the engine team, and we think this bug is not fixed yet, despite one of the possible causes being fixed. And we need your help.
Are you still able to reproduce the issue? If so, are you willing to collaborate with us to collect as much data about the issue as possible and help us fix it?
This question is for anyone who has this issue now, or has found a workaround but can still reproduce it.
Hey, thanks for reaching out to us directly on the forum!
From my side, I can say that none of the in-game tools show any issues with the game.
The logs generated after manually closing the game via Task Manager do not show any errors or freezes—they only indicate that the game was closed. This is simply because the game freezes entirely and cannot be closed any other way.
The only clues are left in the Windows Event Viewer.
I included such clues in my report about this issue, as well as in other reports regarding this problem.
Here is a report from one of the users, where I described my observations using WinDbg and Windows Event Viewer:

That was about 7 months ago. Since then, I stopped playing so intensively and encountered this issue less frequently.
I also don’t remember if I had this problem over the last month—I simply haven’t played enough. I’ve also stopped tracking logs and Event Viewer. When I get the chance, I’ll check if the issue is still happening on my end and try to provide as much data on it as possible.
Well, I found an old Event log. Maybe it will be helpful:

Hello hhf232,
I have the same issue, BUT using Bazzite (Linux 7.2.9) distro, KDE Plasma 6.7.5
Every time I use ALT+TAB while in a game or even in the hangar, the game freezes 90% of the time and can’t return to normal, this is followed by a crash, with the option to submit a report.
I’m in fullscreen mode.
The logs:

When I play War Thunder, I have the following programs open:
Feel free to send me a private message on the forum if you’d like more informations
For me the issue got resolved during one of the patches made to the live server around the same time that the last dev server was running. Since then I haven’t had the issue.
However weirdly enough during the launch of Aces of Thunder the issue was happening there until they released a patch soon after which also resolved that issue.
If you encounter the issue, could you please do the following:
Create memory dump file in the right-click menuI will write a bit later about how to send us this file.
This way, we can get more context about the state of the process and hopefully diagnose and fix this issue.
Thank you for your feedback!
From what I remember, it wasn’t possible to create a memory dump—at least not from the aces.exe file.
I think I have a memory dump, but from the WinDbg tool. However, these files are from the beginning of the year when I was creating the bug reports.
I will try checking your crash dump from the issue, and I am also going to look into why you can’t make a proper dump from aces.exe
Also, for sharing dumps:
For protection of your privacy (since you are sending contents of your memory), you should encrypt the file before sending.
How::
age utility: GitHub - FiloSottile/age: A simple, modern and secure encryption tool (and Go library) with small explicit keys, no config options, and UNIX-style composability. · GitHub (from releases or by the readme instructions)age.exe -r PUBLIC_KEY -o DUMP_NAME.dmp.age DUMP_NAME.dmpTo get the PUBLIC_KEY, write to me in private messages on the forum and I’ll give it to you
DUMP_NAME is the name of the generated dump
After that, send the encrypted file however you like.
