[Wayland1.5]CPU occupancy rate of Weston is 99%

[Yang Andy]

Hi everyone
When i run QT-Application on wayland/weston,sometimes there is NG issue that CPU occupancy rate of Weston is 99%.
The probability of this NG issue is very low,but if the NG issue occur,CPU occupancy rate of Weston retains 99%.
Could anyone give me some advice on how to track the NG issue of weston?
And what factors could cause this issue?
Best regards.
