UI Bug in WEB interface

Basic Information:

Printer Model: RatRig VCore3
MCU / Printerboard: SKR Pro

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed

Describe your issue:

Not so long ago my UI goes mad - low contrast manu and white menu bar. After refreshing the page on second everything looks ok, but then this bug appears again.

UPD: Telegram Bot also stopped launching. Only hand-restart starts it

Neither of these are Klipper issues. You should report to Mainsail and the telegram bot developers.
