blurred chart and other things...

Hi.

Finally the 3.8 to play around... :)

I have the following issues:

1. as per screenshot, the chart becomes blurred after I change the timeframe more than 2-3 times. I use Renko chart. (By the way, still not possible to see closed trades on Renko...)
2. Moreover: Are you planning to add Heiken ashi indicator to built-in indi? I am using an old one created by a user years ago. it works good but in my opinion it would be better a more updated recent one (for libraries)
3. After 20-30 minutes of usage, cTrader piles up a huge amount of RAM and becomes unusable. I am forced to close and restart to make it good. In my configuration I have the following indicators on:
   3 EMA; Heiken Ashi, Daily pivot; Awesome osc; Fischer; Draw spread; crosshair sync; sync objects; auto drawings

It is the same configuration I have on Tradingview.

Thank you.
