Flickering Issue on Playback + Export

Hi Everyone,

I'm new to DaVinci Resolve Studio and working with the latest version. I'm have strange problems when using Color Mode - the image flickers randomly when I use playback or adjust settings - going from the applied grade back to the raw, Arri Mini MXF footage. I have the same problem when I export. However, when I'm using playback in Edit mode, the video is clear.

It seems like a video card issue but I'm not entirely sure. I'm working with the latest CUDA drivers. Please help! Many thanks.

Hi AntonJosef,

I have the same problem here.

After davinci 15.0 released, my first issues was stabilization with GPU crashed 100% every time.

On davinci 15.1 this issues only start after a while using davinci.

Also noticed that when this playback issue, "flickering graded clips" starts, davinci also crashes on clips stabilization using GPU, and I have to kill task to close davinci.

The clips are H.264 codec 1920x1080 59.940fps

Hardware
I Have 24gb of ram
CPU Intel i7 X990 4000MHz

Nvidia 1070 GTX
Nvidia 680 GTX
The graphics driver is the latest 399
And all system is updated.

Only work with SSD WITH RAID0

No issues on any other software, the system is perfectly stable, temperatures and memory usages are very low.

I tried a lot of configurations, cache no cache, the issue always starts after a while.
Could be some combination of configurations on davinci preferences and my hardware, but I just can't figure out what is causing this.

Thank you.
