Total canvas memory use exceeds the maximum limit (256 MB)

[danikupers]

Hello,

After scanning multi QR codes after each other (tried on different iPhones 7,8, 12) with Browser Safari , we are getting random (not every time after the same amount of scans) an Console error: Total canvas memory use exceeds the maximum limit (256 MB), it doens't want to scan than anymore.

I'm using the continously modus

Is there any solution for this?

I have the same issue on the latest iOS 15. I leave the camera constantly on for scanning and then after a while no QR codes will be detected anymore.

Only on iPad's.

In some cases I see this message appearing in the iPad console logs: "Total canvas memory use exceeds the maximum limit (736 MB)" in VueQrcodeReader.common.js:9221

Looks like there is a memory loop.

Yes i think its a memory loop. I couldn't fix it, so i used an external barcode scanner (bluetooth, click on on iphones) with vuejs , many times faster.
