crash when canvas functions related calls are issued

[vitasynergy]

Hello, I'm using a Makerfabs 4.3" capacitive touch based on ESP32S3, hardware version 3.1 (here's the product page https://www.makerfabs.com/esp32-s3-parallel-tft-with-touch-4-3-inch.html)

The display works fine when the gfx-library is being used without the creation of a canvas, below the gfx-library declarations: Arduino_ESP32RGBPanel rgbpanel = new Arduino_ESP32RGBPanel( 40 / DE /, 41 / VSYNC /, 39 / HSYNC /, 42 / PCLK /, 45 / R0 /, 48 / R1 /, 47 / R2 /, 21 / R3 /, 14 / R4 /, 5 / G0 /, 6 / G1 /, 7 / G2 /, 15 / G3 /, 16 / G4 /, 4 / G5 /, 8 / B0 /, 3 / B1 /, 46 / B2 /, 9 / B3 /, 1 / B4 /, 0 / hsync_polarity /, 40 / hsync_front_porch /, 48 / hsync_pulse_width /, 88 / hsync_back_porch /, 0 / vsync_polarity /, 13 / vsync_front_porch /, 3 / vsync_pulse_width /, 32 / vsync_back_porch /, 1 / pclk_active_neg /, 16000000 / prefer_speed */); Arduino_RGB_Display gfx = new Arduino_RGB_Display( 800 / width /, 480 / height /, rgbpanel, 0 / rotation /, true / auto_flush */); . // Init Display gfx->begin(); gfx->fillScreen(BLACK); gfx->setTextColor(WHITE); gfx->setFont(u8g2_font_fub42_tf); gfx->setCursor(100, 100); gfx->println("\n01-setup-pre-setRotation");

Then as soon I add the Canvas declaration to the above gfx declarations: *Arduino_Canvas gfxCanvas = new Arduino_Canvas(800, 480, gfx);

and the canvas usage instructions (commenting the instructions of the gfx): // Init Display gfx->begin(); /* gfx->fillScreen(BLACK); gfx->setTextColor(WHITE); gfx->setFont(u8g2_font_fub42_tf); gfx->setCursor(100, 100); gfx->println("\n01-setup-pre-setRotation"); */
gfxCanvas->begin(); gfxCanvas->fillScreen(BLACK); gfxCanvas->setTextColor(WHITE); gfxCanvas->setFont(u8g2_font_fub42_tf); gfxCanvas->setCursor(100, 100); gfxCanvas->println("\n01-setup-pre-setRotation");

gfx->setRotation(0);                                
currRotation = gfx->getRotation();
Serial.print("\n02-setup-currRotation : ");
Serial.println(currRotation);

gfxCanvas->setRotation(0);                                
currRotationCanvas = gfxCanvas->getRotation();
Serial.print("\n02-setup-currRotation Canvas: ");
Serial.println(currRotationCanvas);

gfxCanvas->flush();

It crashes as below:
