Short description of error
if you have two monitors and one has 100% scaling while the other have 125% for example, when changing the workspace some ui parts will have the wrong size until you hover your mouse on the panel

Exact steps for others to reproduce the error

Have the monitors with different scaling, in my setup the main one is 125% and the secondary is 100%
Have two blender windows, one in each monitor
Change the workspace from any to animation(for example)
Check the timeline UI and hover your mouse on it right after

I don't know if it's just me, but there is a problem with the video, it stops in the second 0:06.
Is it the same problem described in {#85476}?

@mano-wii - that video was almost unusable for me too. But in the last few seconds of it I think they are showing us that items in the middle of Timeline header shift horizontally to a new center only when moused over. Although it looks like item hovering I am guessing that is just entering the area, so probably doing a refresh then.

But I have not been able to recreate this on my multimonitor Windows setup so only guessing.

not sure, the problem isn't with the cursor, its with the blender layout

@Diogo_Valadares - yea, this is the problem that im having

But that is very difficult to tell from your description and glitchy 33MB video. Better instructions that illustrates this problem for me:

Open blender (factory settings) on any monitor with normal 100% scaling.
Select "New Window" from the "Window" menu and drag the resulting window to a different monitor that has increased scale (in this example 125%), then ignore that one.
At this point the original window (on the 100% monitor) looks exactly as we expect it. Image added for later comparison:

Now click on the tab at the top to change to the "Animation" workspace:

As shown above, there are layout issues as this window is drawing the text in a font size that is really meant for that other window. Moving your mouse into each area will properly draw each one in the expected font size:

So we definitely have code in place that draws the interface text at different sizes depending on that monitor scale, but with this particular process the font size is not reset correctly between monitor draws? in the captures you will notice that the toppar header is not shown, but this would be related as it just doesn't fit in that vertical size at the requested font size.

Now that I can see this I might be able to look into this eventually, but probably not in the near term. So I don't mind taking this one if there isn't a fire under it and I can't get to it for while, like summer. LOL

With @Harley's description I can now understand the problem.
I think it is worthwhile to either update the description or create another report in order to confirm and keep track of this problem.
I will do this...
