Whatsapp video call issue in update 170

Facing Whatsapp video call issue in update 170. Whenever someone or myself does whatsapp video call, after few mins they report that my video quality is poor but I seem them fine. Sometimes, when call starts they dont see my video.
It never happened before, and I remember the only change was this update to 170. Its been 1-2 weeks and everytime it happens. Need ipfire developer to look into this. Never happened before. Ipfire running in VM in esxi in rasp pi4
