Nobody uses similar type of arc-based progress bars in TGFX ? ;)

Anyway, I've remember, I had similar problems with Riverdi 10 (see this video here https://k00.fr/RiverdiFLicker )And my solution was to remove Riverdi TouchGFX RTOS task (in CubeMX) and create/start it manually in my app manager as last task, and i...

It seems your seetings is correct, anyway try to play with h/v sync width (pdf says h: 1-140 / v:1-20) ) + LTDC clocks between 40 - 70Mhz. + yes, it's LVDS display, so check your LVDS -> LTDC converter circuit

Strange, 745-DISCO (4.3" 480x272) uses LTDC clocks around 10Mhz, same kit but 5" 800x480 already needs around 20-30Mhz. And if you have even bigger resolution, you need higher LTDC clocks in principle....Anyway, do you have some datasheet for that ki...

If yours LTDC settings for display are correct, what about LTDC clock ? For 1024x600 you need at least freq around 50-60Mhz - see example bellow - Riverdi 10.1" uses 57.92Mhz
