🐛 Opening paywall built on revenuecat's platform increases RAM usage to 1GB

[rubenspessoa]

Describe the bug

I’m seeing a severe performance regression when presenting a paywall built with RevenueCat.
• The paywall takes a noticeable moment to appear (janky / laggy during the transition) and after presentation (toggle behaves specially laggy), and the UI remains sluggish after it’s on screen.
• Memory usage spikes from ~58 MB to 1 GB+ after opening the paywall twice (after first run, it goes up to ~350mb).
• CPU usage also spikes above 150%.
• I ran Instruments (Leaks) and didn’t find any obvious leaks.

I’ve attached a screenshot showing the memory/CPU jump. Any guidance on what might be retaining resources or triggering this load would be appreciated.

Steps to reproduce

I simply try opening the paywall I've built on my account at the revenuecat platform.

on the first time, it increases the memory usage to ~350mb.
on the second time, it increases the memory usage to 1gb+.

Hi @rubenspessoa, thanks for your report! We'll be taking a look and get back to you shortly.

[rubenspessoa]

Thanks for looking into it @rickvdl! if you need any more info, I'm happy to help

[rubenspessoa]

@rickvdl I set the sdk's version to 5.39.0 (the same as I have on my job) and the paywalls perform better with that version. Just saying that in case that helps. I'll keep using this version for now 🙏

[vegaro]

@rubenspessoa how are you presenting the paywall? We copied your paywall into our testing project, and yeah it's not super snappy but the RAM stays more or less the same, which is interesting 🤔
