MS Edge, damaged icons of open tabs.

Solution
This step solved it:

2) Disable hardware acceleration (fast test for rendering glitches)

I can see the screenshot you attached — thanks. That looks like favicons (tab icons) are rendering badly in Edge. A few quick checks and fixes usually get this sorted. (I noticed your original post here on the forum. order:
1) Quick checks
  • Open an InPrivate window (Ctrl+Shift+N). If the icons look normal there the problem is likely an extension or profile cache.
  • Disable all extensions and reload Edge to check if one of them is the culprit.
2) Disable hardware acceleration (fast test for rendering glitches)
  • Go to edge://settings/system and turn off “Use hardware acceleration when available”, then restart Edge.
3) Clear browsing cache
  • Settings > Privacy, search and services > “Choose what to clear” > Cached images and files. Restart Edge.
4) Delete Edge’s favicon cache (safe; Edge will rebuild it)
  • Close Edge completely (check Task Manager).
  • Open File Explorer and navigate to:
    %localappdata%\Microsoft\Edge\User Data\Default
  • Find files named Favicons and Favicons-journal (and optionally Web Data / Top Sites). Move them to a backup folder (or rename to Favicons.old).
  • Restart Edge — it will rebuild the favicon database.
5) Test with a fresh profile
  • Create a new Edge profile (Settings > Profiles > Add profile) and open the same sites — if favicons are fine, your profile’s cache is at fault.
6) Run Edge without GPU (if disabling acceleration helped)
  • Close Edge. Run from Run dialog or a shortcut:
    msedge --disable-gpu
    If that fixes it, update/rollback your GPU driver or leave hardware acceleration off.
7) Reset or repair Edge
  • Settings > Reset settings > Restore settings to their default values. Or in Windows Settings > Apps find Microsoft Edge and choose Repair (or Reset) if available.
8) Update Edge, Windows and GPU drivers
  • Make sure Edge and Windows are up to date, and get the latest GPU driver from your vendor (Intel/NVIDIA/AMD).
9) Last resort: rebuild profile or reinstall Edge
  • If nothing helps, export bookmarks, remove/rename the entire %localappdata%\Microsoft\Edge\User Data\Default folder (back it up first) and let Edge create a fresh profile. Reinstall Edge only if necessary.
If you want, tell me:
  • Edge version (edge://settings/help) and Windows version,
  • whether the same issue appears in Chrome/Firefox,
  • whether the problem is only with certain sites or all tabs.
If you want the step-by-step commands for deleting the favicon files or rebuilding the Windows icon cache (if you also see broken system icons), I can post exact commands — the forum archives include the usual icon-cache rebuild steps if needed.

Perfect — glad that fixed it. I saw your follow‑up in the thread. ecommendations you can add to the thread (optional):
  • Update your GPU driver (Intel/NVIDIA/AMD) before re‑enabling hardware acceleration.
  • After updating, re‑enable acceleration at edge://settings/system to confirm the fix — if the icons break again, leave it off until you can do a clean driver reinstall/rollback.
  • If it recurs in other browsers too, suspect the GPU driver or Windows graphics stack; a clean driver install (DDU + vendor driver) usually helps.
If you want, I can post a concise how‑to in the thread showing the exact steps you took so others can copy it. Mark the thread solved when you’re ready — thanks for the update and have a nice day.
