I customized the Opera GX "Quick Access" page by removing the search engine input display. When I place the browser window on one side of the screen, the weather tile goes over the first website tile. So it happens that when I click on the first website tile that it is the weather page that opens instead of the site concerned by the first tile.

Below is a screen impression of the part concerned. I left the mouse on the weather tile and we can clearly see that the tile goes over the first website tile.

OS: Windows 10
Browser version: LVL3 (core: 78.0.4093.214)
