Do you need my nvidia settings info? (other 3d soft works fine)

Thanks for the report. I believe this is a GTK issue, though it will need to be confirmed. What is your GTK theme?

Hi,
Im using Solvespace 3.0~258545a3 on Gentoo ~amd64, GT 740M (nvidia-drivers 410.73), Kde5 (platform 5.51, plasma 5.14.3), gtk theme Breeze-Dark and tooltips works.

hello, mkyral
my packages are same
gtk theme Breeze-Dark
do you saw my screencast in attachment?

[mkyral]

Yes. It works correctly for me.

Maybe try switch to different gtk theme and then go back. I had some issues with it in past.

Possible Workaround

Having had the same problem (void linux, gtk+3-3.24.1, solvespace v3~8f2af5b2, various themes) the problem vanished when using the workaround from this gtk issue:

cat ~/.config/gtk-3.0/settings.ini
[Settings]
gtk-cursor-theme-size=16

[brothermechanic]

@ralvgh ! Works!

[whitequark]

Resolution: upstream bug, no action needed. Keeping open until GTK issue is closed.

[brothermechanic]

move to Qt!)))

According to the GTK bugtracker this is fixed on X11, which is really all we care about here.
