Reproduce the issue in the call panel and compare its avatar rendering with the avatar shown in Room Info. Locate the frontend components responsible for those two views, then verify that the call-panel avatar matches the Room Info quality on Windows and that the reported reproduction steps no longer show a blurry image.
