ToolTip remains over popup window in Win11 22H2
Bug explanation
Description
When a tooltip is shown and a popup window is opened, the ToolTip remains iff the mouse is also positioned above the popup.
Steps
- Position the mouse above a control with a ToolTip (and also where the popup will appear)
- Use a keyboard shortcut to open a popup window
Reproducing the bug
I tested the behavior on different systems. It seems it only shows up in Win11 22H2 so far.
| Host | Windows Version | Reproducible |
|---|---|---|
| A (RDP) | Win10 22H2 19045.2130 | No |
| B (RDP) | Win11 22H2 22621.819 | Yes |
| C | Win11 Home 21H2 22000.1281 | No |
| D | Win11 22H2 22621.819 | Yes |
| E | Win11 21H2 22000.1219 | No |
| F | Win10 21H2 19044.2251 | No |
| G | Win10 22H2 19045.2251 | No |
Unfortunately the machines running Win11 21H2 denied upgrading to 22H2. So I couldn't test if the buggy behavior shows up after the upgrade on those systems as well.
Version
4.6.1
Hi @hakito this is really great testing! Thank you! A couple follow up questions.
- Which version of .NET are you targeting?
- Does the same issue reproduce without the Material Design library? There are a number of ToolTip related issues in WPF that could be contributing.
ad 1. it's net48
ad 2. I was not yet able to create a demo-app without MDIX to reproduce this issue, but we will work on this
