Thanks, this bug is fixed now.

3d-illusions commented 4 years ago

awesome!

3d-illusions commented 4 years ago

Hi bug is still there if origin is window rather than region, and even if the origin is set to region, when you change to a different workspace the ovlerays start bouncing around again (even though your overlay isn't visible)

The main reason of this issue is a lack of API in blf module. If there is a way to get original font size, this issue will be fixed.

Do you have any ideas to realize this? I also posted the question to blender.stackexchange.com.

I'm not sure. You might have more luck getting an answer at:

unrelated question. Do you know how to get information about what the mouse is hovered over? I need to find the area, panel type, parameter/property id/name, or any other UI element identifiers.

Thanks. I will post the question later. If it is difficult to solve this issue, we will need to downgrade this add-on.

Do you know how to get information about what the mouse is hovered over? I need to find the area, panel type, parameter/property id/name, or any other UI element identifiers.

This should be discussed in other place. I think you can use area.x or area.width for finding area, as well as region.x or region.width for region to find area and region where mouse is placed. But I don't have any ideas to get parameter/prop_id/name.

BTW, this bug is also found in Shortcut VUr. Perhaps, we should report this to Blender developers. I doubt if this is a problem of Blender itself.

nutti commented 4 years ago

Reverted old commit. I think we should simple program which reproduces this phenomena, and direct to D.B.O.

Because Blender 2.91 is alpha, we can also wait official release.

@3diuk

I could easily reproduce this bug by below simple add-on.

https://gist.github.com/nutti/6d06ee1ab43cc9b6d02e14988f62ba3b

The point is here. If we change blf module font size, we can see same issue.

3d-illusions commented 4 years ago

yes definitely, I think you should report the bug ASAP.

nutti commented 4 years ago

I posted the bug report to D.B.O.

https://developer.blender.org/T81757

If you have any additional information, feel free to comment there.

3d-illusions commented 4 years ago

caused by this perhaps?

https://developer.blender.org/D9107

nutti commented 4 years ago

@3diuk

Yeah, I also think this seems to cause the issue.

nutti commented 3 years ago

This issue now fixed in Blender 2.91 Beta (b0f34eee30c4), so I will close this issue. If the issue still exists, please reopen this issue again. Thanks.
