BUG: VR borderless build crash

daltongd · February 17, 2017, 3:54am

Hi guys, just a quick bug report on a thing that wasted about 2 days of development of our game a week before the release ;D

Steps:

Create an empty c++ project (should be the same in blueprint project)
Set the Use Borderless Window and Start in VR to true (in my case I had Should Preserve Aspect Ratio set as well)
Package
Launch in Steam VR mode
The project might launch just fine, but if the engine tries to initialize while the Steam VR is launching you’d probably hit an assert and the game would crash. The worst thing is that it occurs randomly probably depending on if UE4 and Steam VR initializations interfere with each other (e.g. they are run in a wrong order or at the same time) - these are just suspicions, the cause might be different, but the clue is this ‘Use Borderless Window’ flag.

A quick fix for now is to disable ‘Use Borderless Window’ flag.

The assert looks like this (might not be exactly the same, I don’t have access to the code right now):

check(InResource && InResource->Target == Target);

Dump from log directing to the error (just cut some project-specific data and logs according to sound):

Hello daltostronic,

Thank you for the information provided, however I was unable to get the crash that you are seeing on your end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

Can you reproduce this issue in a clean project?
If so, could you provide a detailed list of steps (including any small steps that may have been left out of your original post) so as to reproduce this issue on our end?
Could you provide screen shots of any blueprints/settings that may be involved with this issue?
Could you provide the complete call stack that is given from the crash reporter (including login/machine ID)?
