Crash in RecoverFromLostDevice

[ubgitty]

Hi

We are experiencing crashes of our app which are caused by device lost events.

What is the proper way to handle a device lost event? Even the provided templates crash when trying to recover from a lost device.

We tested the device lost handling as suggested by the Win2D team by disabling the display adapters in the device manager (https://microsoft.github.io/Win2D/html/HandlingDeviceLost.htm)

Hi, thanks a lot for reporting this! I believe this is a recent regression in ANGLE itself. The template should be able to recover from a device lost as-is.

We have a plan to fix this, and I'll reply back to this issue when the fix has been submitted to ms-master.

Thanks again! Austin

Thanks again for reporting this issue! It is fixed in both master and ms-master. The fix will also be available in the next NuGet package, which should be released soon.

This is now fixed in nuget package v2.1.13.

Thanks again for reporting the issue!
