What "them"? The KDE folks? Apple? I thought Qt4/KDE4 was unsupported.
I gather Qt4 has -graphicssystem { native | raster | opengl }
If I just run
open -a kshisen
it blinks. (that's the shell open command, which with -a is invoking the Mac
app bundle whose name follows)
If I run
open -a kshisen --args -graphicssystem raster
(what's after --args is passed to the binary within the app bundle as command
line arguments without being interpreted by the app launcher)
it also blinks.
If I run
open -a kshisen --args -graphicssystem native
it does NOT blink - at first glance, it looks fine.
If I run
open -a kshisen --args -graphicssystem opengl
then text appears, but all the graphics are blank until I move the window (!),
at which time it's fine.
Seems like it may be using the raster option as a default, even if Qt4-mac is
not built with the +raster variant. That may be at the level of the configure
script doing that now, I don't know, haven't dug that far, never looked at Qt4
internals before.
Supposedly raster could have been faster than native on some platforms, so I
suppose I can see that it might have become the default. But I don't see that
native was slow, although kshisen is not demanding, and I may not have run it
before on this relatively new hardware back on High Sierra, so I might not
notice speed anyway.
