Jagged screen display in smartphone browsers (2.2.7)

[shiromofufactory]

In recent versions, HTML apps created with Pyxel now fill the entire screen when viewed on a smartphone. This is great!
On the other hand, the accuracy of dot rendering has become coarse. To elaborate, there seems to be a difference in the magnification per pixel.
I am posting two screenshots for comparison: the first is the latest version and the second is the previous version (every pixel is displayed at equal size).

ver. 2.2.7

ver. 2.2.1
