after rendering problem

[Fares31099488f4ms]

There's a problem after putting transition and exporting the video the transition does not good 
but after changing the rendering from GPU to CPU it works but with more slower rendering speed than the GPU speed

[Richard van den Boogaard]

Usually, that problem is a result of a firmware version of the GPU. Please share more details on your system specs and/or try to update (possibly downgrade) the firmware version of your GPU.

Thanks.

Try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the latest Studio Driver (NOT the Game Driver).
