Impossible to change console text font size and vid_fps font size (con_scaletext)

GZDoom 4.8.0 x64 / Win10 / AMD_Vulkan

Steps:
1) Run GZDoom
2) Start any map
3) Open console
4) Type "con_scale 3" and "con_scaletext 3"

Actual result: text is small:

Expected result: text is big:

5) Type "con_scale 4" and "con_scaletext 4" (or 1 2 5 6)
6) Try to change any scale options in "HUD / Scale" section of options menu

Actual result: nothing changed
Expected result: fonr size should be changed

NOTE: behavior was ok in 4.7.1, bug appear in 4.8.0
