Re: [Gtkwave-users] Cursor not visible in OSX High Sierra

[<by...@nc...>]

I tried a rebuild using a somewhat different gfx rendering codebase.  The zipped app bundle is here: http://gtkwave.sourceforge.net/gtkwave-hs.zip

This is an experimental version that uses cairo routines intended for the future gtk3 version of gtkwave instead of the gdk-wrapped x11-flavored ones that gtkwave has been using since gtk-1.2.  Let me know if you're seeing the same problems or if there are new and different graphical glitches.  That bundle is compiled and linked against gtk2.

Side note...  I already have a largely functional gtk3 version of gtkwave that I just got working but the gtk3 toolkit has some very weird bugs (that's on Linux!) with widget sizing that I either need to figure out the workarounds to.  I'm guessing gtk3 requires additional function calls to be #ifdef'd in, but for all I know the toolkit has some compatibility issues.  For the Mac, I'll stick with gtk2 unless it proves to be broken with newer versions of OSX: it's real painful getting the GTK-OSX build environment working.

I've had to patch things in GDK in the past in gdk/quartz and it looks like Apple has somehow broken things again that interface to this:

I got these two by clicking around to try to snap to grid. Nothing appears. Then I zoomed in one step by clicking the + magnifying glass. The artifact appeared in the zoomed in view. Then one click in the waveform view to grab focus and the artifact disappears.
