Someone better start the 2016 wish list pronto

My wish would be the same that I have every year: a true Mac version instead of something that just happens to run on a mac.

here's a better example (warning: 1.2 MB)

example.skp

Thanks for taking the time to try and help. I oversimplified the example. I will UL a better example this evening.

My target usage for all of my models requires that I use a single png texture file. Many require an Alpha channel for a portion of the model. This can require days to weeks of trial and error. There has to be a simple solution.

The attached file is a box with a window. Half of the window is 100% Alpha (that works), half is 50% (that does not work.)

....difficult issue to debug, as it appear to be local to your machine.

That's it! Boy do I feel silly. Deleted the .plist files, restarted, problem solved!

Sorry to have troubled you, I should have thought of this sooner.

Do you notice any artefacts in any other applications?
What about Fredo's tools - he uses similar technique to draw the UI as I do.

no problems with other apps or fredo's stuff

sketchup (and only sketchup) itself crashes a lot

it may, in fact, be the most poorly written high profile app ever--they know there's something terribly wrong or they wouldn't have two different, simultaneous, autosaves! (And neither of them work as advertised!)

That is very strange. What are you hardware specs? What is the graphic card?
Is it possible to update the graphic driver - or is that done automatically by OSX?

2010 Quad-Core 2.93 GHz i7 iMac
16GB RAM
ATI Radeon HD 5750 1GB Graphics Ram OpenGL 3.2

Can not upgrade driver

@thomthom said:

I'm baffled.

Could it be an OpenGL issue, hardware? If you disable hardware acceleration under Preferences - does that have an effect?

Ok, this is just weird:
Turned off HA
Dialog says: The change will take effect for new windows
Toolbar returns in the existing window
However, now it's gone again regardless of HA setting! (I even tried restart.)

I may need to reinstall the OS--not fun

@thomthom said:

hm... And your monitor resolution is larger than 1133px wide? Or, is your viewport that wide?

Sketchup.active_model.active_view.vpwidth

And if you have the Ruby Console open while you use Vertex Tools, do you see any error messages appearing?

Sketchup.active_model.active_view.vpwidth
1766

no errors in console

Ok - lets debug that toolbar:

Can you please type:
TT_Vertex.settings

TT_Vertex.settings
#<TT_Vertex::Settings:0x169d16f4 @section="TT_Vertex", @cache={:remember_uv=>true, :view_normals=>true, :context_menu=>true, :radius=>0.0, :vertexinfo_x=>615, :axis_lock=>false, :normal_size=>20, :vertexinfo_y=>234, :gizmo_visible=>true, :l10n=>"en", :vertex_size=>6, :merge_tolerance=>0.393700787401575, :last_select_tool=>:rect, :last_tool=>"T_Select_Rectangle", :toolbar_x=>1133, :axis=>:local, :auto_smooth=>true, :ss_cos=>false, :toolbar_y=>202, :initial_tool=>"T_Select"}>
