Slider stays connected to the mouse at full screen

[Calahan99]

If mpc-hc x64 is in full screen mode and I move the slider at the bottom with the left mouse button to the side,
the slider remains connected to the mouse (as if I keep holding the button), until I click into the video with the left button.

This happens since 2.3.4.17.x64 The last working version seems to be 2.3.4.x64
x86 Versions doesn't seem to have the problem. Newest 2.4.0.x86 is working correct.
Correction: I now have the same problem with the x86 version. Strange.

Windows 10 Pro, 22H2, 19045.5371, Windows Feature Experience Pack 1000.19060.1000.0.

I don't understand what exactly you are doing. Just single-clicking the seekbar, or dragging? Does it need to be a specific spot?

Classic or modern theme?
Which video renderer?
Exclusive mode?

Strange, I now have the same problem with the last x86 version.

In full screen, I drag the slider on the bottom to any side and after releasing the mouse button, the slider is still connected to the mouse so you scroll to the times of the video. Clicking with the left mouse button into the video, it stops the video and after
another click it resumes to play normally.

I just deinstalled the x86 version and this time I selected to not keep the settings.
I will do some more testing and if the problem persists, I will try to answer the last 3 questions. :)

After deinstallation and not keeping the settings, MPC-HC now shows an other scrollbar at the bottom.
If I do a right click in fullscreen, I'm now getting a context menu. With old setting nothing happend.
With old setting, I only got a single line (sometimes with chapter marks as vertical lines) with a small slider.
Now I'm seeing the 3 lines, which I also see when I'm not in fullscreen mode.

I found the setting, which produces the problem. The problem is there when I click on "D3D Fullscreen".
Only difference is, that the scrollbar now has a white background, it was black before.
It's the only setting I needed to change to produce the problem after a clean install.

"Use Modern Theme" is activated
Output -> DirectShow Video -> Enhanced Video Renderer (custom presenter)
Didn't found "Exclusive mode" so far.

When I disable the Modern Mode, the background of the slider is darkgrey now (as before) but the problem is the same.

I can reproduce with D3D fullscreen.
