Instead of trying to write an explanation, here is a video of the issue. There are blank boxes/menu areas where text and other information should be displaying.
This issue only occurs when using WebKit based browsers. I don’t have this issue when using a Chromium browser. Where can I report such an issue?
This started happening with the new 4.8.2 firmware update for the GL-MT6000 (Flint 2). It only happens in the VPN dashboard screens shown in the video, as far as I can tell. I don’t see this issue anywhere else.
