ESP32 memory problem with wifi

[CatDog11]

Hello,
I have a few problems with my little esp32 - touchscreen - project. I got an error with "region `dram0_0_seg' overflowed by 16792 bytes". This error occurs only, if I use both initialition lines in setup:

WiFi.mode(WIFI_STA);
touchscreen_setup();

But in my opinion the memory should be enough, because if i only use one of both the memory remains under 50% of all memory.
Perhaps someone can help me.

Best regards.
