DR14 lag on CentOS when duplicating clips

PostMon Sep 11, 2017 9:02 am

I have noticed a strange issue while using Resolve on CentOS. First, check this screencast to understand what is happening.



As you can see, when I try duplicating an audio clip (using Alt and drag) when 'Show Audio Waveforms' is checked in the Timeline View Options, there is a lag that happens until Resolve reloads the waveform on the original clip and the duplicate. With 'Show Audio Waveform' turned off, it either works fine, or just lags for milliseconds.

This seems to be a CentOS only issue, as I have tried it with Resolve on Windows using the same machine, and that doesn't happen.

I have a feeling it is a GPU issue, although I don't quite understand why the same GPU would be working fine on Windows 7, but not on CentOS.

The reason I think it is a GPU issue is, when I install Resolve and it gets to the point of checking my hardware, on Windows, it says that everything is ok, while on CentOS, it shows a warning (yellow triangle with an exclamation mark) on the GPU. I am not sure why that happens, but Resolve can see the GPU and the NVIDIA drivers are installed.

Any idea why that might be happening?


System specs:
Resolve version: 14.0.0.078
OS: dual-boot (Windows 7 & CentOS 7)
CPU: Intel i7-4790k 4GHz Quad-Core
RAM: 32GB
GPU: NVIDIA GeForce 770 2GB

There doesn't seem to be a video at your posted link. Has it been obfuscated somehow?

The post Peter pointed to also mentions providing logs, and that would be helpful in this scenario.

Fixed the link issue.

I thought you only need the logs for when Resolve crashes. No problem, though. As soon as I go back home, I will upload the logs.

I have narrowed down this issue a bit more.. It seems to be happening only when I am trying to drag an audio clip (or duplicate it by Alt+dragging) to a new track. Disabling the 'Show Audio Waveforms' option makes it slightly better, but what gets rid of it completely is if I create the audio track before dragging the clip to it.

Hope this helps.
