Zotero bad interraction with GeForce Experience.

Hi,

I'm currently writing a bachelor's thesis, and I'm new to Zotero.

Today my whole system seemed to be crashing when I opened Zotero, stuttering and freezing like I have never seen before. It took about 5-7 seconds each time, with the mouse pointer lagging and jumping around the screen as I moved it.
This post explains my experience perfectly:

Playing around with this lag, I noticed that it would start either when switching window or if any part of the mouse pointer even touched the Zotero window.
Opening task manager, I see that it mainly influences my GPU, freezing it, dropping it to zero, and then stabilizing. I always have GeForce Experience Instant Replay running on my desktop, which means my GPU is usually running at 16%, but whenever the cursor hits the Zotero window, the computer freezes and droppes the GPU to 0% for a few seconds.
Turning off GeForce Experience Instant Replay removes all issues.

I would love for someone to try to replicate this.

I also hope this helps someone. :)
  • Check the NVIDIA settings for any app-specific settings. Zotero is based on Firefox, so setting it to use the same settings as Firefox may help.
  • A similar problem, that occurs on some Nvidia hardware, can be fixed with the following steps:
    1. Start "Nvidia Control Panel"
    2. From the column on the left select "Manage 3D settings"
    3. Select "Program Settings" tab
    4. Next to "Select a program to customize" press "Add"
    5. Select Zotero on the list or use "Browse" to find it, then confirm with "Add Selected Program"
    6. From the box below "2. Specify the settings for this program", find "Monitor Technology" and select "Fixed Refresh".
    7. Press apply at the bottom of the screen
    8. (Re)start Zotero
    I'd give it a try to see if it works with Instant Replay enabled.
