我很遗憾听到你遇到了麻烦。我从来没有见过这个错误，所以这只是我的猜测，但我怀疑由于某些原因，表示网格工具或重量工具大小的圆圈一直在显示。当你调整网格工具的大小时，在视口的中心会出现一个圆圈，如下面的截图所示。
I'm sorry to hear you're having trouble. I have never seen that bug, so this is just my guess, but I doubt that for some reason the circle which indicate the size of the mesh tool or weight tool is showing up all the time. When you adjust the size of the mesh tool, a circle appears in the center of the viewport as shown in the screenshot below.

你能告诉我们在那个圆圈出现之前，你做了什么手术吗？
Could you tell us what operation you performed before that circle appeared?

你能不能也试着调整一下网格工具的大小，看看圆圈有没有变化？
Could you also try adjust the size of the mesh tool and see if the circles change?

嗯，这有点奇怪，但我很高兴听到现在圈子消失了。你能告诉我们出现问题的版本和没有出现问题的版本的具体版本号吗？到目前为止，我还没有遇到同样的问题，但也许其他人会遇到类似的问题。

Hmm, that’s weird, but I’m glad to hear the circle disappears now. Could you give us the specific version number of the version that had the problem and the version that did not have the problem? I have not encountered the same problem so far, but perhaps others may experience similar problems.

谢谢你提供的信息! 如果问题重现，如果你能在这里再次发帖，我们将不胜感激。谢谢你给我们回信!

Thank you for the information! If the problem reproduce, we would appreciate it if you could post here again. Thank you for getting back to us!

谢谢你的报告! 我很高兴你发现切换网格工具可以解决这个问题。

在预期的行为中，当你进行其他操作时，圆圈显示应该不可能留在视口中，所以有可能还是有问题。我们想检查一下条件，如果能重现这个问题的话，就可以修复它。

Thank you for your report! I'm glad you found that switching the mesh tool solves the problem.

In the expected behavior, it should not be possible for the circle display to remain in the viewport while you are performing other operations, so it is possible that something is still wrong. We would like to check the conditions and fix it if we can reproduce the problem.

单击";"符号会导致出现圆圈，但是没办法关闭，3.8版本就有这个问题 我一直以为是可以关闭只是我没找到办法，原来是BUG？

@jyou 感谢你的报告，我们终于能够重现这个问题。 问题似乎是，默认情况下，"; "被分配了一个热键来减少画笔的大小，但使用这个热键后，画笔的显示仍然存在。
Thanks to your report, I was finally able to reproduce the problem. The problem seems to be that ";" is assigned a hotkey to decrease the size of the brush by default, but the display of the brush size remains after using this hotkey.

这个问题可以在最新的测试版（4.1.26-beta）中重现，所以我们希望在未来的版本中修复它。
This problem can be reproduced in the latest beta version(4.1.26-beta), so we would like to fix it in a future version.

恐怕我们不能修复3.8版本，但有一个变通的办法。它似乎可以通过打开网格工具视图来解决。另外，如果你不经常使用画笔，你可以编辑hotkeys.txt来删除热键的分配，以防止它再次发生。
I'm afraid that we can not fix 3.8, but there is a workaround. It seems to be fixed by opening the Mesh Tools view. Alternatively, if you don't use brushes often, you can edit the hotkeys.txt to remove the hotkey assignments to prevent it from happening again.

I have created an issue ticket for this:
https://github.com/EsotericSoftware/spine-editor/issues/650

We've fixed it in 4.1.27-beta and it has been released. Please update and check if the issue is solved.
