Improved Rendering is causing my Gallery Items to disappears, swapping back to classic corrects.

I have a checklist app that I have created.  It is loading a list of 25 questions from a sharepoint site of around 70 entries.  When under classic mode it renders perfectly, but when it is switched to Improved Rendering (which seems to be happening automatically now) the scrolling from my IOS device causes the gallery items to disappear.  Please advise.

Hi @rliles 

Can you share some details with your issue?

1. which controls does the gallery contain?

2. what is version of PowerApp studio?


That seems to be a memory issue that PowerApps Teams are fixing, a batch of memory improvement has landed with Studio version 3.19094. Please update your apps to take advantage of these, especially if your app is Gallery heavy.

The fix is expected to be deployed to all production regions the week of October 21.

If it is not already, please ensure the Use longer data cache timeout and background refresh setting is disabled in App settings -> Advanced settings.

The above workaround refer from @_Corey_ , For more information, please check out this thread:


Best regards,


1)  The gallery has 6 labels, 1 checkbox, 1 html text, 3 icons, 2 text boxes, and 1 radio button.

2)  I am using the web interface, so I was assuming that was the latest and greatest.

I wanted to add one thing...  I removed all the controls in the gallery except for 2 labels and I still saw the same behavior.  Items disappear and only 14 of the 25 items are being show.  In classic mode all items are shown and they do not disappear when scrolling.
