0.99.6: Image is not antialiased when zoom % matches HiDPI scaling

[iemon]

XnView: MP 0.99.6 - 64 bit
OS: Windows 10 Home 64-bit ver. 21H1
Display Settings:
Resolution: 3840 x 2160
Scaling: 150%

If I zoom images to 150%, antialiasing is not working while antialiasing is working at 149% or 151%.

Setting environmental variable QT_AUTO_SCREEN_SCALE_FACTOR to 0 (or running with -noDpiScaling) fixes it but icons are small and a little hard to press.
