Input lag bug in programs like Blender

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



On my system, programs like Blender have very noticeable input lag that
makes it hard to use. It happens no matter what Linux distro or
compositor I try. At first the only fix that seemed to work was
installing the proprietary amdgpu-pro drivers on Ubuntu. Running "env
LIBGL_DRI3_DISABLE=1 blender" seemed to help, but it still wasn't
perfect.

However, I recently found out how to truly fix it on any distro with
the open source drivers. If I create a file called .drirc in my home
folder with the contents:

<driconf>
  <device>
    <application name="Default">
      <option name="vblank_mode" value="1"/>
    </application>
  </device>
</driconf>

then restart my system, it fixes the issue. I'm not sure what this
does, but it seems like there's some sort of bug here.

I found out about this fix from this thread:

I'm running Manjaro Budgie, and this is the ouput of inxi -Gxx:
