There were breaking changes to LVGL in 2026.4.0 that are outlined in the changelog for that version. You might want to check that. Without your YAML, I’ll offer the same generic advice I offer for any ESPHome major version upgrade. Try cleaning the .esphome and .platformio folders (the former is in with your YAML most likely, the latter tends to be at the root of the user directory) and try again. Sometimes there are some cached things in there that aren’t happy after an upgrade, and a fresh download can help.

There is a fix for that in dev, will be in the next point release, out shortly.

Perfect, thanks
