Alt + tab crash with Intel HD 4000 graphics card

[yellowbase]

0 a.d. 0.19 runs fine until I switch to another task with alt-tab or simply go out of the full-screen mode to see the desktop. the crash happens every time I do so.

[elexis]

Can you still reproduce this issue? What is your operating system? Alt+tab seems to indicate windows and we didn't have any similar reports. Please reopen this issue if you have further information.

[Michael]

I would like to reopen this bug. With Alpha21 and Windows 7 64-bit the game crashes every time I press Alt+Tab or the Windows key (very annoying as it is right next to Ctrl). 0 A.D. does not crash if the start screen ("Learn To Play" / "Single Player" / etc.) is shown, only once the match has started. Alt+Enter switches between Fullscreen and Windowed Mode as expected.

With Alpha21 on Ubuntu 16.04 no crash happens if the Windows key (aka Super key), Alt, or Alt+Tab is pressed. The game simply continues in the background and I can change back to it.

Details: unhandled exception (Access violation reading 0x00000018) Location: unknown:0 (?) Call stack: (error while dumping stack: No stack frames found) errno = 0 (No error reported here) OS error = 487 (Attempt to access invalid address.)

[elexis]

Someone with VisualStudio should check out this crash dump. Considering #4181, Stan's testimony "Alt tab has always been buggy on windows." and some other tickets where this has been reported, we shouldn't ignore this one in theory.

[Imarok]

Hmm I cannot reproduce it with windows 7 64-bit and A21.

Possibly a duplicate of #4361, if you have a dual monitor.

[Michael]

the crash happens on my Lenovo W530 laptop, no dual monitor.

Intel HD 4000 + NVIDIA Quadro K1000M

[Michael]

Ok, I have some more information. My Lenovo W530 has two graphic cards (Intel HD 4000 + NVIDIA Quadro K1000M), but the crash only happens with the Intel HD 4000. In case I start 0 A.D. with the NVIDIA card, Windows key and Alt+Tab work as expected!

Btw, if I connect my laptop to the docking station with two external screens, 0 A.D. plays fine with Nvidia, but the Intel HD (using latest drivers available) still crashes on Windows key, etc.

[Palaxin]

This happens to me, too (ALWAYS when using Alt-Tab or losing focus of 0 A.D. in the Windows GUI). The last time a few days ago with SVN.

I use Windows 10 64-bit with an Intel HD 4400 and do not use dual monitors.

[echotangoecho]

This definitely seems like a driver issue. Can anyone with Intel graphics and Windows try to reproduce this (ideally with a debugger attached?).

[Stan]

I'd like to have a crash dump for that.

​Forum thread.

[Stan]

Can't reproduce. Were you guys playing, were you on battery ? were you using the integrated card or the nvidia card ?

The bug is not reproducible by any developer so unfortunately we won't be able to debug this quickly enough for the new release. We hope to get to the bottom of it at some point...

[Stan]

So visibly it occurs on W10 1607 (I have 1703) and seven as well on both skylake and third generation Intel.

Not sure if Henry had an Nvidia card.

I guess you want to ref #4682 ?
