Yes. Now everything works as it should. Thank you.

Increasing the tile size will cause memory issues and indeed might lead to a reboot.
What is the actual pixel width of your display?

This is a display from Siemens C55. Actual pixel size is 101*64

I have created a new constructor "U8G2_PCF8812_101X64".
Can you do a test, whether this works better?
The code is available in the latest beta release 2.35.17
You can download the latest U8g2 beta release from here: https://github.com/olikraus/U8g2_Arduino/archive/master.zip
Arduino IDE:
- Remove the existing U8g2_Arduino library (https://stackoverflow.com/questions/16752806/how-do-i-remove-a-library-from-the-arduino-environment)
- Install the U8g2_Arduino Zip file via Arduino IDE, add zip library menu (https://www.arduino.cc/en/Guide/Libraries).
PlatformIO:
platformio.ini (https://docs.platformio.org/en/latest/projectconf/section_env_library.html#lib-deps) should include
lib_deps =

The new library did not work because the display initialization was not changed. In the file u8x8_d_pcf8812.c you need to put
static const uint8_t u8x8_d_pcf8812_96x65_init_seq[] = {
U8X8_START_TRANSFER(), /* enable chip, delay is part of the transfer start */
U8X8_C(0x21), // PowerON, ExtCommandSet
U8X8_C(0x09), // Internal HV-gen x3
U8X8_C(0xB7), // Set Vop
U8X8_C(0x16), // Bias n=2 //15
U8X8_C(0x06), // Temperature coeff 2
U8X8_C(0x20), // StandartCommandSet
U8X8_C(0x0C), // normal mode, display non-inverted
U8X8_END_TRANSFER(), /* disable chip */
U8X8_END() /* end of sequence */
};I wrote this in my first message. After the replacement this code everything worked great. There is no garbage.

Unfortunately, this option without editing did not work either. I edited the u8x8_d_pcf8812.c file a little and everything worked again.
Added a function - static uint8_t u8x8_d_pcf8812_101x64_generic(u8x8_t *u8x8, uint8_t msg, uint8_t arg_int, void *arg_ptr)
And the last line of this file
return u8x8_d_pcf8812_96x65_generic(u8x8, msg, arg_int, arg_ptr); replaced with
return u8x8_d_pcf8812_101x64_generic(u8x8, msg, arg_int, arg_ptr);
