Failling to reload QRCode with big URLs

[pedrobertao]

When dynamically resetting the value for the QRCode, it fails when the value string is too big.
Example:
First I have this:
https://www.foo.io/big-foo/#/send?to=XXXXXXXXXXXXXXXXXXXXXX
QRCode loads correctly.

Then I update the value to get something like
https://www.foo.io/big-foo/#/send?to=YYYYYYYYYYYYYYYYYYYYYY
QRCode doesn't reload.

Workaround: Clear value (set value to ' ' i.e.) and then set the new value.
It doesn't work if I simply replace the new value with the old one.

I solved this problem,by change the QR background color! For example, bgColor #000 to #333
