Font Corruption Issue on the “Select User and Enter Password” Screen
On the “Select User and Enter Password” screen, even though I set the language to Korean, both English and Korean fonts appear corrupted. Occasionally, after reporting this bug, the fonts display correctly.
Today, I discovered the reason behind this. I use a laptop and a Samsung Bluetooth mouse. When I turn on the laptop without turning on the Bluetooth mouse, the fonts display correctly. However, when I turn on the Bluetooth mouse before powering on the laptop, the fonts are corrupted most of the time, with approximately a 90% chance of occurrence.
Sometimes, on the password entry screen for login, my language, Korean, displays correctly. Based on my observations, I believe there may be an issue in Lubuntu related to the Bluetooth mouse.
