Glitch with controls inside cards

还没有人认领这个 Issue。

### Bug explanation

It appears that there is a visual glitch whenever a certain controls are clicked on dark theme (when they're inside a card).

An example:

```



```

**Results (when inside a card):**


**Results (when I put the exact same code outside of the card):**


Same thing with a DataGridView when it's inside the card (it's not that apparent, but you can see the glitch on the left side of the sort arrow:


This also happens with the Light theme switched ON.

What could be the problem here? I'm suspecting its the window hosting this UserControl, but I'm not sure where to start looking.
If I host these buttons on a dialog, or something, they work just fine.

### Version

4.5.0

首先，使用 issue 中描述的深色和浅色主题，在卡片内外复现所报告的 Button 和 DataGridView 行为。比较 4.5.0 版本中的视觉结果；当卡片内的控件在两种主题下都能正常渲染且不出现所报告的故障时，即表示完成。
