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.
