[PD] Gem crashes after relaunching with error: i965: Failed to submit batchbuffer: Invalid argument

to correct my previous statement, when I wrote metro is slower 3 times I
was wrong, it is not 3000ms but 3333ms but it is due to my last project
where I used 200fps for the Pylon high speed cameras.
now everything seems to make sense: when I used those USB3 cameras with the
correct 200fps, this metro phenomenon did not occur, until I changed the
cameras to webcams keeping accidentally the 200fps. when turned it off Gem
went back to 20fps.
Thanks for solving this mysterious case :)
