Open CL Issue

After adjusting 20-50 photos, additional adjustments will cause the screen to black out for a second before the display returns. At times it will washout gray with full screen flickering to back and white. Heavy use of local adjustments seems to be the biggest culprit. Turning off open CL display will stop this but of course compromises speed. I use an NVIDA 660 Ti with current drivers on an Intel i7 3930k 6 core with 32g ram.
Fix is to close Capture One and re-open.

I have never seen this with 8.xx. Has anyone else seen this on 9.x?

  I've just been re-working some old Canon 40D shots. I upgraded their engine from v8 to v9 and was adjusting various settings (mainly exposure) when the viewer started blanking out to a black image for a second or two after each adjustment.
  
  Looking in ImgCore.log, there are a number of CL_MEM_OBJECT_ALLOCATION_FAILURE and CL_OUT_OF_RESOURCES messages.
  
  I thought this problem had been fixed, but it's definitely occurring again in v9.2 ☹️
