Intermittent oversized app icons in GNOME app grid

After a recent update, icons in the GNOME app grid occasionally appear significantly larger than expected.

The issue is intermittent:

  • Sometimes icons render at normal size
  • Other times they appear oversized
  • It can “fix itself” without a clear trigger (by restarting shell, or after some time)

Steps to reproduce

Currently inconsistent, but observed during:

  • Opening the app grid (Activities → Show Applications)
  • Switching between workspaces or reopening overview

Additional Notes

  • Issue started after a system update (last week)
  • Appears to resolve temporarily without manual intervention
  • Not yet confirmed whether extensions are the cause

Has anyone else experienced this behavior on GNOME 49, particularly on Wayland?
