The call to `resize` is pretty important... without it, nothing shows up
on the screen when I run flameshot (presumably because it's 0 pixels by
0 pixels large). This was accidentally removed when resolving merge
conflicts in 77c509e798.
While I was in here, I also opted to delete some comments. I personally
am never a fan of commenting out code: if we need something, that's what
Git is for! And, just in case GitHub disappears, I thought it would be
nice to record my research in a Git commit about why I think removing
`Qt::BypassWindowManagerHint` is ok. Comments copied from
https://github.com/flameshot-org/flameshot/pull/731):

Later, I investigated how things behave on Linux with a non-tiling
window manager:
