Scroll freezing

[anton-zaicev]

@SamBent,
I have issue related to already fixed bug: KirillOsenkov/MSBuildStructuredLog#407

Same actions are needed for the scroll freezing (DPI > 100%, virtualizing enabled with "Pixel" scroll unit). This behaviour seems to be related with one of the recent updates of the PresentationFramework.dll (current version I have is - 4.8.4360.0), but not sure about it.

The key thing for now is that UseLayoutRounding property is involved. When I use UseLayoutRounding="False" for the container there is no any freezing, but with "True" value I have scroll freezing every time.

Here is the scroll trace with infinite scroll calculations loop which I had collected:

Thanks, @anton-zaicev. Could you provide a minimal repro project?

Here it is: ScrollFreezing.zip

Repro is very simple: set DPI to more than 100%, open the app and scroll with the mouse wheel - done!

Update: bug is not related to the recent update of the PresentationFramework.dll (4.8.4360.0), I got repro also on the 4.8.4320.0 version.

Can you provide any kind of feedback? Were you able to reproduce this issue with provided project?

I'm busy with servicing requests - it will be quite some time before I can look at this. Consider opening a servicing request for this (by going through Microsoft support, as we've discussed in the past). If it's that simple, it would meet the bar. And that would get it on my radar.
