esp32 5inch display lvgl display glitches when writing to SPIFFS

I have an esp32 5 inch display running an app with lvgl. If all I do is open the Spiffs to write a file and then close it the display glitches , tears for about 300ms. I have been reading it is a psram problem. Does anyone have a fix for this?
