[plunavat]

Hello,

I am using themer 1.2.0.41 with cmd 6.5 and extjs 6.5. This hangs and shows complete white screen every time after one or two changes.
Need to restart everytime...
This is frustrating.. can anybody help

Thanks for the report! I have opened a bug in our bug tracker.

If you would have any additional steps to reproduce it would be really helpful for us. For example what actions were you doing.

//EDIT: We can confirm the issue over Material theme. It seems that it's connected to the extensive operations over the palette. So far I can only recommend to try to keep the work with palette (adding new colors / changing them) to minimum
