Flashing stripes on the screen after downloading parcels from the gallery

The problem started for me after the update on May 2, 2026. When I place a house from gallery , its textures initially look very plasticine-like—this is most noticeable with the trees, which look like trees made of Lego Duplo  (this phase lasts about 1 minute). Then, once the textures have loaded, stripes start flickering on the whole screen.

Sometimes, before the stripes appear, a brief diagram of something like the world pieces (see photo below)

This issue isn't caused by my graphics card, because when I play without downloading the parcels, the problem doesn't occur, and it never occurred before the 2.05 update either. It also doesn't happen in other games. I play with mods disabled.
