System Information
Operating system:windows 11
Graphics card:Nvidia rtx 3060

Blender Version
Broken: 3.0
Worked:never
Short description of error
When using two windows by holding shift and dragging on the corner, the top bar sometimes dissapears
Exact steps for others to reproduce the error
Open blender
Drag the corner of a window while holding shift to add another blender screen
Click an option at the top (modelling, sculpting, layout, etc.)
The top bar that has file edit, render, and all of the workspaces should turn grey. You can get them back by minimizing blender and opening it again, but it is annoying to do that every time you switch workspaces

I'm not able to follow your instructions...

When you shift-drag at the corner of any editor you get a new window containing only a copy of that editor. These windows never have options at the top for "modelling, sculpting, layout, etc" So if you mean to select these options on the main window, I'm not seeing the behavior you describe. I am unable to do anything that makes the top bar "turn grey"

Can you elaborate a bit, include some screenshots maybe?

so the first screenshot is in the layout mode. When I click into a different workspace while I have two screens, the entire top bar turns gray and you can't click it. The second screenshot is in the "render" workspace and there is no top bar on the right. The right was the original screen. I'm not always great at explaining stuff, sorry.

Not sure if you have (somehow) purposely taken screenshots without OS titlebars, or that you have just neglected to say that this issue only occurs when the main window is fullscreen (Window / Toggle Window Fullscreen).

not sure why you think I would fake a bug, but ok. Yes, it is in fullscreen. I didn't realize that it being in fullscreen mattered, but I'll take another screenshot to "prove"it.

@EMGhoulguy - not sure why you think I would fake a bug, but ok. Yes, it is in fullscreen. I didn't realize that it being in fullscreen mattered...

I didn't think you faked anything, just that it being Fullscreen is an important detail in trying to understand what is going on, test it, help you, and fix it. This is also easily tested by taking the window out of fullscreen and seeing if the same issue occurs.

From your screenshot it looks like your other blender window is also in FullScreen? Does this occur if the main window is fullscreen but the others are not?

So now the issue is that when your main window is FullScreen and you have a separate window on a different monitor, this issue occurs when you change workspaces. What are the resolutions of your multiple monitors? are they all the same OS scale?

I have a monitor and a laptop, and both are 1080 x 1920. I have both in fullscreen, but now that I checked it is fixed if either are not in fullscreen. I'm not totally sure how to check the os scale, but I think they are. I've been making this more difficult than it should be, sorry.

In your screenshots above it does look like your two monitors are of differing scale, with one at 100% and the other at 125%?

That is a known issue: #85706 (Lack of workspace font size update when the window came from a monitor with a different scale). I was working on a possible fix, but that stalled when I was unable to reproduce the issue D10483: Fix #85706: wm_window_make_drawable update DPI

So this might be addressed one day, but in the mean time you might not ever experience this if you change anything about your setup, either making both monitors the same scale or not running fullscreen perhaps.

Just right-click on windows background, select "Display Settings" and you will probably see a "Scale and Layout" section. Or click on the Start Button enter "Change the resolution of the display"

I can reproduce this regardless if main window is fullscreen or not. I don't know how to make child window fullscreen though (or did windows just crop screenshot?).

So not sure if this is same issue as #85706 especially if @EMGhoulguy says, that not having main window fullscreen fixes this behavior.

@iss - it is definitely the same cause. It is the differing scales of the two monitors that is at the root of all of it, resulting in text drawing too large on the monitor with the smaller scale. Quite often seen as a temporary thing, drawing normally when the wonky area is next drawn after hovering. Although with top bar nothing is drawn when things overflow in it and it is harder to make that area redraw.

I can reproduce this regardless…

I’d love explicit reproducible steps. I was able to fix this in D10483: Fix #85706: wm_window_make_drawable update DPI but the solution needed work but I stopped being able to recreate this error so couldn’t continue.

My steps were:

2 monitors:

No. 1 - left side, 1920x1080, 100% scaling, this is windows main monitor
No. 2 - right side, 1920x1080, 125% scaling, secondary monitor
Start Blender on monitor 1
Open general template
Toggle fullscreen window
Make new 3D editor window by Shift+dragging corner
Move it to monitor 2 (I have maximized it, not sure if necessary)
Click through workspaces on main window

If this is same root cause, I will merge these reports.

Thanks Richard! If I follow these instructions exactly I do see it once again, which hopefully will let me get back at fixing it.
