Thanks again for the report. In my system it appears (it's the gyro copters, pic below that I just took with latest version). So I may ask, what system did you tried? Thanks.
Ok, I got something that may help you, thanks to Per-Ola Eriksson that had the same problem and found that the emulator settings caused it. So, the emulator settings to fix it should be: CPU and FPU = Aproximate A500/1A1200 , must be "on". and Chipset = Cycle exact on FULL. Collision Level also on FULL.
