Selecting an EQS Testing Pawn that has some EQS set, while running in DX12 mode, causes a crash. Happens both on 4.9.1 and on today’s master branch.

In 4.9.1 it gives a Crash Reporter screen without much info; in source-compiled 4.11 it gives this message:

59971-error.png

[Here][2]'s log.

Note: works normally on DX11 mode.

Update: enabling Show Navigation also crashes in dx12 mode.

Also crashes when Anti aliasing is High or Epic. Details here.

By way, my VGA is a MSI Radeon 390, driver 15.8 beta.

Hi Ixiguis,

Thanks for report! I was able to reproduce this crash in both 4.9.1 and 4.9.2, and I’ve updated an existing bug report for issue (UE-20995) with details you’ve provided. I’ll post here if I see any update. Thanks!

I just wanted to update that it is still crashing in 4.10p2.

Except for TXAA, which doesn’t crashes now, but doesn’t works right either (leaves some ghost images behind).

Hi Ixiguis, we think this is now fixed on 4.11 (even though we couldn’t repro in-house).
