Hello
I have one console and one slider.
In the main loop, a character is inserted in console. GT1 timer update the slider current position.
With #define GDISP_NEED_SCROLL TRUE defined in gfxconf.h , from time to time I can see a missing character on console, right after console scroll.
If I move slider position fast, I see more lines with missing first character, and sometime touchscreen stop responding, until hardware restart of the board.
#include "gfx.h"
GTimer GT1;
static GHandle ghConsole;
static GHandle ghSlider1;
uint8_t i=0;
void callback1(void* arg) {
(void)arg;
gwinSliderSetPosition(ghSlider1,i);
}
static void createWidgets(void) {
GWidgetInit wi;
// Apply some default values for GWIN
wi.customDraw = 0; wi.customParam = 0; wi.customStyle = 0; wi.g.show = TRUE;
// Create the console
wi.g.width = 50; wi.g.height = 200; wi.g.y = 20; wi.g.x = 20;
ghConsole = gwinConsoleCreate(NULL, &wi.g);
// Set the console colors
gwinSetColor(ghConsole, Yellow);
gwinSetBgColor(ghConsole, Black);
// create Slider1
wi.g.width = 50; wi.g.height = 200; wi.g.y = 20; wi.g.x = 100; wi.text = "";
ghSlider1 = gwinSliderCreate(NULL, &wi);
gwinSliderSetRange(ghSlider1,0,255);
// Clear the console
gwinClear(ghConsole);
}
int main(void) {
// Initialize the uGFX and the underlying system
gfxInit();
// Set the widget defaults
gwinSetDefaultFont(gdispOpenFont("UI2"));
gwinSetDefaultStyle(&WhiteWidgetStyle, FALSE);
gdispClear(White);
// Attach the mouse input
gwinAttachMouse(0);
// Create the widget
createWidgets();
// initialize the timer
gtimerInit(>1);
//continious mode - callback1() called without any argument every 250ms
gtimerStart(>1, callback1, NULL, TRUE, 100);
while (1) {
gwinPutChar(ghConsole,'0'+i%10);
gfxSleepMilliseconds(100);
i++;
}
return 0;
}Does anyone can help me to understand what's wrong ?

Hi
I tried with GDISP_NEED_CLIP as FALSE in gfxconf.h and the symptoms continue.
Kind Regards,
