> wm4, Vincent: can you try setting QT_AUTO_SCREEN_SCALE_FACTOR=0 ?
QT_AUTO_SCREEN_SCALE_FACTOR=0 works with -12, just like with -10.
I suspect that different behaviors are due to the fact that among
HiDPI cases, screen sizes, DPI's, etc. are different.
The patch consisted in truncating instead of rounding to nearest,
so that it might have solved the problem for users where the
real factor was between 1.5 and 2, thus changed from 2 to 1
when converted to integer, 1 meaning no HiDPI (for which there
are no issues) if I understand correctly.
I suppose that my real factor is between 2 and 2.5, so that truncating
gives the same result as rounding to nearest. Hence the same behavior.
I don't know what broke for wm4. "With the patch applied, it scales
to 1, which is nonsense." is not very meaningful. This is what happens
for low DPI, for which no issues have been reported.
