After updating to DisplayFusion 12 Beta 8, I noticed that Firefox has become extremely slow, especially with network access.
- Up to Beta 7, there were no issues.
- With Beta 8, Firefox’s network performance is heavily impacted.
- If I exit DisplayFusion’s background process, Firefox runs normally without any problems.
Has anyone else experienced this behavior?
In the past, there was a known compatibility issue between DisplayFusion and ESET, and I’m wondering if this might be a similar case.
Additional Information:
- ESET version: 19.0.14.0
- Windows version: 11 25H2 (26200.7309 Preview)
- Firefox version: 145.0.2
- Disabling ESET protection while running DisplayFusion did not resolve the issue.
Any feedback or confirmation from others encountering the same problem would be appreciated.
I was able to reproduce something similar here, we'll take a look into it and see what we find.
Thanks!

It seems the issue has been resolved with Beta 9. Thank you.

Seems I have the same issue. I tried latest Beta (9) of DF but it did not change anything. If I exit DF, then FF seems to work fine. Else it takes several seconds (5 or more) before a page is loaded.
FF: 146.0
Eset: Small Business Security 19.0.14.0
Windows 10: 22H2 19045.6691

Same issue here: Task Manager shows DisplayFusion using up to 20% CPU for no reason on Beta 10.
@UnderPL1 Are you on Windows 10 as well?

Yes, I would also like to report DisplayFusion taking up to 90%+ CPU usage when a large number of windows are open. I had around 15 VLC windows open (not playing) and close to 50 IrfanView windows. Windows 10 handled it fine, but DisplayFusion made my PC slow to a crawl.

I updated to DisplayFusion 12.0.1, but there still seem to be compatibility issues with Firefox and ESET.
When using Firefox and selecting an image in a form (for example, when uploading an image via a browser), it takes an abnormally long time only when DisplayFusion is running.
The environment is Windows 11 Pro 25H2 (build 26200.7462).

Not only Firefox has performance issues. Quotes in MetaTrader 5 freeze every few seconds. Additionally, the icon for the “Status Window” in Hard Disk Sentinel no longer jumps to the taskbar on the monitor where that window is located. That’s all I’ve noticed. The last version that worked correctly was 11.2 (beta 7).

After reinstalling DisplayFusion, the issue is no longer occurring.
I’m not sure whether the reinstall fixed it or if something was updated on ESET’s side.
For now, I’ll continue to monitor the situation as it is.
