This works amazing. Thank you so much!
Im also having the same issue when it tries to highlight the snap location with the little circle. It does not update the screen but still snaps to corners or ends but does not show the little circle in the correct spot. Any chance you have the same issue or have a similar script to fix?
Thanks again for this one!!

@Royrdan I'm glad that it helped somebody!
I'm also having the same issue with midline and crossline snapping. Unfortunately SketchUp is not throwing events in this case (or at least I could not find such) in order to repaint the screen. If you zoom enough, then screen refresh works fine for snapping.
I'm also annoyed by CPU usage of SketchUp in Wine, but it is usable.
By the way, credits go to @DSDev-NickHogle. I just expanded what he has started.

@itsanov Thank you for your terrific work here. I was going crazy with the one mouse click delay to refresh the screen...I'm running SU 2017 Make under Wine 5.10. I had the same issues, but with your extension installed it has magically solved that problem!

I still see some lag in retrieving the endpoints, mid-points, etc. when trying to select an object, but it does seem better when I zoom in. All in all, this is not a huge deal and it seems like I can now run SU2017 on my Linux Mint 20 (Cinnamon) system just fine!

Thank you very much!

@Royrdan @mackinlay53 and everyone else using SketchUp under Wine, I have updated the script to fix the slow Import. I have also added a possibility to enable/disable the refresh fix from Plugins menu.

Hi @itsanov I tried out the new script today, and I find that it seems much quicker and snaps much better/more accurately to endpoints or midpoints when drawing new geometries. That may be my imagination, but it was working quite well today. As for my remaining issue, when changing View / Edge Style from Shaded with Texture to Monochrome, or vice versa, the screen does not update until some other event occurs (like zooming in or out). I assume SU throws some event for this change in Edge Style, but it does not look like your script is reacting to it. But other than that I am so happy to be running Sketchup under Wine on Linux Mint 20....your script is fantastic!!! Thank you very much for your contributions here. Thanks, ...Patrick

Hi Patrick,
Style changing should be OK now.
Best,
Ivo

Thank you very much. This is a great help.

Thank you very much. This is a great help.

Nice to hear that, YEN! Thank you!

Perfect script! Thank you so much @itsanov !
For those who wonder how to make rbz from rb, just do this:
zip fix_sketchup_wine.rbz fix_sketchup_wine.rb

Very good work, Thanks.

How do I install this?

@dgm
Make a file "fix_sketchup_wine.rb" as above.
Place the file in /Plugins filder,
in my case :~/.wine/drive_c/users/y/Application Data/SketchUp/SketchUp 2016/SketchUp/Plugins/
Hope this helps.
