desktop app is slow and indicators disappearing

Hi guys, 

v.5.2.5, i've been experiencing slowness on performance on desktop app and the indicator window becomes blank, no matter what indicator I use. I have to force close the desktop application and re-open it again to see the indicator window (bottom). Also when I'm changing around indicators, it too becomes blank and I have to force close it again and re-open,

Please fix.

Thanks
