Hi everyone, I found a working workaround for the MT5 UI lag issue (Build 5572) when using EarnForex Position Sizer / Position Size tools.

Symptoms: candles/ticks update normally, but the MT5 terminal becomes very laggy when moving/resizing the window (UI stutter), and the problem disappears as soon as you remove the Position Sizer from the chart.

Fix / Workaround (confirmed on Build 5572):

  1. Open Position Sizer → Inputs

  2. Set ShowMainLineLabels = false

  3. Change the label font to Arial (or another simple font like Tahoma/Consolas)

  4. Restart the terminal (optional, but helps sometimes)

After disabling the main line labels and switching to Arial, the UI lag completely stopped on my side.

It looks like the slowdown is related to chart text/label rendering in the latest build, so disabling those line labels avoids the heavy redraw calls.

Hope this helps — it fixed it instantly for me.

 
I solved it by copying the files from the previous version to the destination folder. Just copy the files from the previous version to the destination folder. Make a backup of the folder first.

I just want to share that one indicator was the cause of this problem in my case and that is Breakevenline indicator, as soon as I remove from my chart, legging issue resolved and if i add it back , chart start to freeze again.
Thank you very much. I've removed the breakeven indi and now all works nicely. I appreciate you sharing the solution, because metaquotes help is non-existent.

On my Mac, MT5 is completely frozen. I can’t click anything or perform any action. The platform is unusable.
