glyph background causing vertical line (fillheight) with custom font

[MomePP]

Hi,
I got an issue while trying to padding text as a picture below. It creates black verical line after setTextPadding() is being used (_fillbg is set). I've try to debugging with PADDING_DEBUG flag.

Currently, I found out that a variable fillheight was declared as unsigned int16. In my case, this value goes negative and fill rect with height 65535, so it appears as vertical line.

After changed the variable to int16_t, it's fixed my issue. I'm not sure, it supposed to changed this variable type or it's fault from a custom font that being used.

TFT_eSPI/Extensions/Smooth_font.cpp

Line 434 in 24b0e88

uint16_t fillheight = 0;

BTW, a custom font that i used is Baloo2 regular with font size 12, I've created by using your pde script.
Here is my converted font baloo2_regular_12.h.zip
I notice that there was only some characters such as f or i that cause the issue. (gdY more than maxAscent 😵‍💫)

Dev. environment

• PlatformIO
• ESP32 with arduino-esp32 master branch
• TFT_eSPI version 2.4.61
• ST7735 1.8" with SPI interface, no touch controller

Thank you in advance.

Thanks for reporting this and finding the bug, yes the result can be negative so your solution is correct.

I have updated the master library.
