Ratio not displayed properly on 3440x1440

[wxrl]

• LCD Display Spec 3440x1440 pixels

• Installation Command:

sudo ./install.sh -b -t tela -s ultrawide2k

• Grub Configuration (/etc/default/grub) after Installation

GRUB_GFXMODE=3440x1440,auto

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
GRUB_THEME="/boot/grub/themes/tela/theme.txt"

• Actual Display Results
  • Resolution of background picture (/boot/grub/themes/tela/background.jpg) confirmed as 3440x1440, and the actual display of the background seems proper.
  • Icons and fonts seem wider (stretched) than normal as shown in the picture. Also icons and fonts are bigger than expected (regarding the default font size set in tela theme), and fonts are NOT smooth...

Tried with changing GRUB_GFXMODE=3440x1440,auto to GRUB_GFXMODE=3440x1440x32,auto as well as GRUB_GFXMODE=3440x1440x32 and re-mkconfig by sudo grub-mkconfig -o /boot/grub/grub.cfg, but neither improved.
