Seeing this in logs for wallet chart -

[15:27:27] [warning] [main.prerequisites.hpp:92] [1003327]: qrc:/atomic_defi_design/qml/Wallet/Main.qml:516: ReferenceError: chart is not defined

Stuck on

No crash during tests (rapid change from wallet to DEX where selections both have chart) on Linux.

LMK how best to test this otherwise - Was this mostly an issue on M1 Macs? I cant cover that test case here.

Indeed it was mostly present on M1 Macs, but @Milerius told me that he was able to reproduce on Linux

No crashes detected here yet, seeing chart on wallet now.

Any chance we can avoid the white defualt white background flickering on change in dark mode (lite mode is ok)?

Yeah sure, I can make the web view hidden until it's fully loaded

Just got a crash on Windows , logs attached.

Just noticed that on wallet page, if switching to a different coin that has no chart (e.g. RICK/MORTY), the previously loaded chart is still displayed.
In earlier versions, it would display as below instead

[smk762]

On dex page if switching from pair with chart to pair without, can we extend the lower section?
