Windows size error?

Thank you, we all like scrcpy and your job.

scrcpy V4-V4.1 -> scrcpy V3.3.4

scrcpy V3.3.4 -> scrcpy V4-V4.1

Hi, using same command line with two versions.

scrcpy.exe --max-fps 30 -b 50M -s zte.local:5555 --keyboard=uhid --video-bit-rate=2M --no-audio --window-width=526 --window-height=1138 --window-x=527 --window-y=31

scrcpy.exe --max-fps 30 -b 50M -s poco.local:35456 --keyboard=uhid --video-bit-rate=2M --no-audio --window-width=526 --window-height=1138 --window-x=0 --window-y=31

V4+ 'have Window Problems':
Size, not 100% set. (why?)
Not Black space (why?)

Start by reproducing the reported Windows behavior with scrcpy 3.3.4 and 4.x using the supplied command lines, comparing the requested window size, position, and black space. Trace the Windows window-sizing behavior in the desktop client and verify that the newer versions honor the same dimensions and placement.
