When using the MQTT the simmilar problem occure. The weight value sometimes shows nonsense number.

I checked this on M5Stack Basic, and these two characters (0x30FC, and 0x30FB) were shown properly. So this is the problem occurs only on core2. v1.8.3 for core2 still has this problem, and I strongly wish It would soon be fixed.

I forgot to add the picture of the screen when the bug happens. This is the screenshot of step 5 [image: 1629056268496-core2bug1-resized.jpg] it seems like a part of M5Img (in a rectangle (35,132, 274,16) is written back onto the text. and this is the screenshot of the code above (right after calling lcd.rect(...) ) [image: 1629056381759-core2bug2-resized.jpg] and the rectangle (35,132,274,16) is overwritten with the background. when you use M5Img instead of screen.set_screen_bg_color, you will see a part of the image instead of the background. in both screenshots, text must be shown without a black/yellow rectangle.

Upon further testing and investigation, my original observation is incorrect. It seems that the blocks are mostly working correctly. It does not seem to be an issue with a specific version either. When I setup a simple UIFlow sketch to "Restart after 10 seconds", the first time I run it it correctly restart after 10 seconds. It then seems that the IRQ register isn't set right because it won't restart again if I immediately run the code again. If I instead power of the Core2 and then power it back on with the button on the side it will then run the code correctly and restart the device. It does not seem to be a hardware issue as the example wake on rtc code in the M5Core2 arduino library works correctly every time.

Sorry, there is no reply for a long time, we will investigate this bug.

thank you feedback. we already fixed this problem.

@delchi said in Possible Bug On Image Hide/Show: Core2Duo Firmware : UiFlow 1.7.4.1-Core2 IDE : UiFlow 1.7.4 What I'm trying to do : Display image 0 ( PNG , in Flash , 330 x 240 36.4 KB ) Wait for Button A to be pressed Hide Image 0 Play WAV file ( SD card ) Show Label0 Wait 5 Show Image 0 What happens : Everything works, with the exception of the image show/hide/show. It constantly shows after button A is pressed. Wave file pays, but no change to the image.

@zontex UIFlow 1.7.4, the bug still not fixed. This makes UIFlow completely unusable on mobile browsers.

I have similar Problems. Burner V2.2.8 M5Paper V1.7.3.1 and 1.7.4 [image: 1617949689750-bildschirmfoto-2021-04-09-um-07.49.07-resized.png]

Perfect !

Yes, the duplicate remain if i save the file, refresh the webpage, or load the program again! But in the meantime I figured out the solution. Just right click to block and disable.

Thank you for your patience
