[Bug]: Flickering #665

Open tavyscrolls opened 2 weeks ago

tavyscrolls commented 2 weeks ago

Frontend Version

1.2.30

Expected Behavior

No flickering

Actual Behavior

'frames' of the UI from the last job (possibly many) flickers in with new ones, forcing a restart of comfy

Steps to Reproduce

Starting with a freshly loaded workflow running in Firefox on Ubuntu, queue a prompt and let it run for a minute. Then any input comfyui receives will cause previous images of the workflow to flicker over the current workflow.

Debug Logs

Terminal doesn't output anything, refreshing or resetting view do nothing, oddly the flickering stops if mouse hovers comfy queue manager though it is equally likely to display old settings as new ones when it stops.

Browser Logs

ComfyUI Front-end version: 1.2.30 index.html:4:11 Empty components: policy ignored components-manager.js:767:11

so nothing, but bringing the console up makes editing settings possible without the flicker. After closing it, the flicker becomes worse than before.

What browsers do you use to access the UI ?

Mozilla Firefox

Other

It hadn't done this until I updated nvidia, comfyui and reinstalled all packages since running last version of comfyui (~1 month old) and the only new extension is the cogvideox wrapper

Have you tested other OS / Browsers?

tavyscrolls commented 2 weeks ago

Would have to install on a completely separate build to test OS, but I installed Brave to check it. The first time, it froze the entire computer, which doesn't happen in Firefox. After rebooting, it ran pretty fine so I left Firefox open for another Brave test and it is definitely an issue related to Firefox, same everything else.

@tavyscrolls it's an issue with recent versions of the Nvidia driver on Linux and hardware acceleration.

you can disable hardware acceleration in Firefox by navigating to about:config and searching for gfx.webrender.software. toggle the setting to true and then restart the browser. Compositing should show as WebRender (Software) in about:support.

not an ideal fix but it seems to work. alternatively, upgrading to the latest git version of egl-wayland may also work too.

edit: removed the part about disabling hardware acceleration in the normal preferences as that does not seem to help.
