System becomes unresponsible sometimes when OpenCL app running

app restart heals it it seems...

Currently to use memory more effectively I allocate/deallocate GPU memory when app go from one big area of computations to another.
Sometimes whole app run goes just fine (~5h), but sometimes all GUI updates in system experience huge slowdown. For example. mouse cursor freeses for 1-2 seconds few times per min.
My application restart heals this issue.
I didn't see such behavior in prev builds, when memory buffers were allocated only once at app start.

Does it mean that GPU memory becomes fragmented in some way and driver can't do needed allocations in GPU memory and start to do trashing to host memory ?
Will this issue be fixed in new driver releases?
