@godswillmesh Switch Opera Mini to Automatic data savings mode and reload. That site doesn't support extreme data savings mode.

Adding for posterity @avl that it appears that when a window's open for a while, even if the white bar does not appear (because I'm actively using that window), the display will become off-calibration with what's on the page, forcing me to move my cursor below where the link actually is to click on the link. The behavior fixes itself if I switch tabs.

I assume the problems are related.
