System Information
Operating system: Windows 10 Professional x64 20H2
Graphics card: GeForce GTX 1080

Blender Version
Broken: 2.92

Short description of error
Just as the title indicates... Save Startup File slightly moves the window positions. This is kind of bad for me because I use a custom layout to work around some of the issues and limitations of the UI. I.e., I need multiple windows with different "Areas" loaded into them, mainly because switching the Workspace using the tabs is a productivity nightmare that massively slows me down.

Exact steps for others to reproduce the error

Position Blender windows in a precise configuration
File > Defaults > Save Startup File
Close Blender
Reopen Blender. Windows have shifted to the right, and sometimes shifted down.

Note that merely closing/reopening Blender preserves window locations. The issue only occurs with Save Startup File.

I’m not able to recreate this with current master (Windows 10, three monitors, arranged horizontally). Can you try this on the latest experimental build to see if behavior has changed? And also give some details on your monitor arrangement (how many, how they are arranged, and which is set main). And perhaps include some “before” and “after” captures that show this movement.

I can reproduce something similar on Kubuntu Linux, build from master. Normally I force window into specific position so I turned that off.

It seems to be related to whether you have borders on your window. Blender may save the "internal" corner and then open up at that location with it's saved size.

Here are normal borders before and after:

If I set Blender to not open with borders then it works fine:

If I set extra large borders around the window it indeed moves down and over:

Obviously Windows and Linux differ quite a bit on how windows are done so might not be exactly related.

@Aaron_F_Ross - Do your monitors differ in scale? Or are they arranged vertically (any monitor above another)?

On Windows with blender 2.93, first test with all monitors set to the same scale. I just placed the main window near the corner of my middle (main) monitor then did Window / "New Window" and dragged the result to my left-most monitor. I then did File / Defaults / Set Startup File. I took a capture and you can see what it looked like in the top half of the image below. The bottom half of the image shows how it looked after closing and restarting blender. The two windows were in identical positions on the two monitors.

I then changed the scale of my first monitor to 150%, but left the middle one at 100%. In this case the window on the middle monitor was still perfect afterward, but the window on the 150% monitor was shifted to the left by a few pixels and down by about the difference in the height of the title bars. Close but not perfect.

Note that it is a known issue that monitors will not be placed correctly when monitor are arranged vertically. Fix for that here: https://developer.blender.org/D10637

Hi Harley,

I have one 4K monitor. In the Windows settings, the UI is at 100% scale. However, I did have the Blender Resolution Scale set to 1.25. I tried setting Resolution Scale down to 1.0, but that didn't help.

It looks like it's just the secondary windows that are not preserving location. The primary window seems to retain its position. But I have a couple of (necessary) windows that I've split off from the main window. This is because I need to access other Area panels without changing the entire Workspace. That's for productivity reasons; I'm a generalist and I need to switch tasks often. The dedicated Workspace tabs are a productivity killer.

Switching to a beta build is not an option for me at the moment, sorry.

Thanks

Actually only hoping you could test on a beta. I made a lot of changes to the way that blender windows are created and especially how they are made on Windows. I have tested with multiple blender windows on multiple monitors and each properly opening their own child windows. So I am hoping that most of your issues are fixed, but would like to know for sure.

@Aaron_F_Ross > I have one 4K monitor.

Ah, I had assumed you had multiple windows on multiple monitors, not on a single monitor. Following is a test on 2.93. Top shows an arrangement I set up, then selected "Save Startup File", then closed blender, restarted and it was as shown on the bottom. No change.

As already requested, having you provide screenshots of before and after would help us help you.

Although placement on a single monitor (as described here) should be perfect with 2.93, placement of multiple windows on monitors that differ in DPI and/or scale should be fixed in this: https://developer.blender.org/D10863
