Buttons and DockPanes will show incorrectly in ArcGIS Pro 3.4

[AquanuityDevelopment]

After we upgraded our program to ArcGIS Pro 3.4, many things went wrong.  Many buttons with size "middle" will only show icons without texts.  DockPanes hosting a winform using WindowsFormsHost will totally mess up the display.  They were working fine before version 3.4.  Hope ESRI can fix these issues soon.

Here are a screen shot of Pro 3.4 and one before Pro 3.4:

Hi @AquanuityDevelopment 

Regarding the WindowsFormsHost : We are tracking this issue as BUG-000172334: In Windows 11, content in a WindowsFormsHost is miscolored or invisible when rendered in a docked dock pane

we are targeting a fix for the 3.4.1 Patch Release.

As you may have found, there are a few workarounds. Switching to dark theme, floating the dock pane, unpinning the dock pane, or connecting over remote desktop will make the problem go away.

Please accept our apologies for the problem and its impact on your users.

@UmaHarano BUG-000172334 has been fixed in the latest version of ArcGIS Pro.  Thank you!  However, ArcGIS Pro 3.4's button layout is still unpredictable. Some "middle" size buttons' captions will simply disappear and make the application looks ugly (see the pictures from my original post).  Do you have any workarounds to fix these kind of issues?  Does ESRI have any plans to address these obvious bugs?

It appears 3.4 doesn't like separators.  After I removed them, the captions display normally now.
