Hello. Created a new TouchGFX Designer (4.10.0 version) project with stmf469 disco application template and started it in simulator - the result was ok, but if I start it on target, using "Run Target" or ST-Link utility the output represents shifted segments and when i touch the screen segments are shifted again differently0690X00000884x0QAA.jpg

Hi @dimka​,

I'm not having the issue with any stm32f469-disco board i have here in the lab. We're basically transferring 4 x 200x480 individual pixel segments to the display in 16-bit applications which is apparent from the your screenshot. I will think about what might be causing this

I tried different examples including from Designer with smaller resolution - the same resullt - shifted and flickering segments. Base ST Demo example works good.
