Preview Bug on Win10 4K Monitor w/ DPI Scaling

I'm getting a bug where a gallery and some other controls are displaying in an incorrect location when in preview mode.  In edit mode the gallery looks correct:



However when pressing F5 to "play" the app, this happens:

I still have to click where the original select icon is, not where it's displayed, if that makes sense.  Hovering over the gallery many times will result in the "real" gallery breaking through as such:

This doesn't happen on other my other 1080p monitors.  I can simply move my browser window over to another monitor and it displays correctly.  It doesn't appear to be affecting the app when executing/playing the app (ie, not editing).

Re: Preview Bug on Win10 4K Monitor w/ DPI Scaling

Hi @goobernoodles ,

Based on the issue that you mentioned, it seems that there is some rendering issue within your canvas app in Preview mode.


I have made a test on my side, and don't have the issue that you mentioned. Please consider set Scale and Layout settings in your Win10 4K as below:


You could also consider change the "Display resolution" option to a lower value, then run your app again, check if the issue is solved.


In addition, please also consider turn off the "Scale to Fit" option within "Screen size + Orientation" option within App settings of your app, then re-publish your app, check if the issue is solved.


Best regards,
