Issue Details

Steps to reproduce:

1. Have Adguard engine running together with ESET anti-virus (protection enabled)
2. Visiti a facebook page like (facebook.com/AdGuardEn) as a logged in user (otherwise all elements are not loaded)
3. Observe if page loads properly and perform reloads (F5)
4. Try do also use browser assistant to enable/disable filtering

Expected Behavior

Page loads properly with every refresh regardless if Adguard filtering for page is enabled or not

Actual Behavior

Page does not often fully load either showing blank white/dark screen or some other visual mess .
Disabling filtering from Adguard assistant does NOT resolve the problem.
Happens with both chromium browsers and Firefox.

Problem resolves immediately if either ESET protection is disabled OR Adguard engine is completely turned off.
Issue only appears if both engines are running.

Screenshots

Additional Information

ESET AV v18.2.14.0
Reproduced issue with 2 separate windows 10 machines
1 machine had a fresh install of Adguard with no previous config.
Don't really know when problem first appeared.

@xtwmx Greetings. The issue persist without the HTTPS filtration (Settings - Network - switch off Filter HTTPS)?

Anyway, we need logs and if its possible, screenshots/screencasts of the bug. Logs can be collected according this instruction:

1. Collect the debug log as it's explained here.
2. Remember the exact time when the issue was reproduced.
3. Send the archive to qa@adguard.com:
   - include [windows] keyword and 5599 in the subject of your email
   - specify the exact time when the issue occurred.

Hi @KolbasovAnton
Disabling HTTPS filtration also resolves the issue. So I can use it as a temporary workaround.
Debug logs (HTTPS enabled) sent with timestamp 21:10
I did more than 5 reloads for the page (facebook.com/AdGuardEn) before I got a successful load.
Usually I get a blank white page.

EDIT: I sent another set of logs since I forgot to enable filtering from the browser assistant.
Since the issue reproduces regardless of the state of the browser assistant status then both logs are valid.
Debug logs (HTTPS enabled) sent with timestamp 21:42

I am having this exact same issue. Wasn't until one of the recent AdGuard app updates.
