There was a problem hiding this comment.
Maybe this should do ImGui::SetCurrentContext(_context); first, to ensure we don't update some other context.

And then set it back later?

Oh and a test for this would be vital -- here it needs to check that&b.atlasTexture() == io.Fonts.TexID. And also &c.atlasTexture() == io.Fonts.TexID, which will notify you that you need to do a similar change in the move assignment as well.

@mosra I updated the PR to reflect suggested changes. Note that I am restoring the original imgui context, which is backwards compatible and also tested by the tests to be the case. |

Awesome, thanks! 🙏 |

I'm so embarrassed, i can't believe i missed this! |

No problem, @Squareys missed a part of this also ... and I should be blamed for not noticing the issues in both PRs ;) |
Hi @mosra !
As mentioned on #61, the move constructor needs to update the pointer to
_texture, otherwise rendering breaks because it uses the then deinitialized texture memory.Best,
Jonathan
