Some window are wrongly rendered after opening
Some windows are wrongly rendered immediately after opening, or after changing focus, or resizing. It is easily reproducible when opening File chooser dialog from various applications, e.g. gedit, evince, firefox. It usually helps to change focus, switch screens, or resize to fix the issue. I see this issue also with gnome-shell top menus. I am on up-to-date Fedora 31 Wayland. This has definitely something to do with the fact that I use an external monitor in addition to internal and one of them has 125% scaling and another one 100%. The screenshots are not affected, thus attaching photos:
