cTrader desktop very laggy after last update!

After last update to version 5.2.11 my workspace became unusable. I've got a lot of indicators, but most are not cpu-intensive. Maybe MA ribbon needs more resources, and maybe tick charts zoomed out max need more computing power, but before the update everything ran smoothly, and now I can't even pan/move the chart normally, it's like moving a rock in a tar, tick refresh is delayed… And cpu and ram are not utilized to the max, I've got pretty good hardware, so it's obviously cTrader issue. Again, before the update everything was ok.

Any way to fix the issue? As for now, the platform with my custom workspace is unusable! 

Please provide some help.
