12.17.4 beta: Parts of location bar in bottom-left corner of screen

There are some changes in Directory Opus 12.17.6 (Beta) which we hope will stop this happening.

Please give it a try, with transition animations turned back on, and let us know if the problem is gone or still there.

Since I turned off ( Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations ) set to false 9 days ago I have not seen it happen
Have installed 12.17b6
Preferences / Display / Transition Animations All on
And set Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations to true
These are the only 2 things that I changed

Have only been using 12.17.b6 for 2 hours and it has already happened again
Also as in first report both listers have become source.

I also changed ( Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations ) to true and I had been using Opus for 9 days with it set to false to me it looks like this setting cause this to happen.
Have changed ( Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations ) back to false to see if it happens again.

Can you think of any kind of pattern about when the things appear at the bottom left?

It seems to be a combination of the transition animations and the mixed dpi mitigations, but the animations themselves don't trigger the mitigation code on their own. My guess is there is an action which triggers both at once, which may be key to understanding the issue.

Toolbar tooltips are one thing which trigger the mitigations, and might appear just as you click on something which in turn triggers an animation. Could it be something like that?

If you can think of anything to try on our end to help reproduce the problem, I'd like to give it a try!

Also, which graphics drivers are you using? I'd like to try with the same drivers and version (assuming I have the hardware to go with it).

Just happened again as I noticed that both listers had become source when trying to copy from right to left with the standard copy button
Copy AS
My graphic drivers are
Nvidia Geforce GTX 1070 27/11/17 Version
Intel HD Graphics 630 18/11/18 Version
I know you kept saying update drivers but I only wanted to change 1 thing at a time If I had changed them all, how would I know which was the problem.
Do you want me to go back to 12.17.b3 as it only started with 12.17b4

The graphics drivers are from 2017 and 2018?

Definitely try updating those, please.

Have updated both graphics drivers will be testing today.
Nvidia Geforce GTX 1070 24/10/19 Version
Intel HD Graphics 630 25/10/19 Version
( Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations ) True
Preferences / Display / Transition Animations All On

Has just happened again.
Not sure when it happened was copying files.
Went to make a brew when I got back screen had locked on logging it had happened
Both left and right lister windows were also source

Is it possible the screen being locked is connected to the other times it happened? That's something I haven't tried. We can investigate in that direction, unless you've seen it happen in situations where the screen could not have been locked.

When you say both windows are source, does that state continue if you change folder? Or if you click on the status bar?

Also, when in that state, do the path fields still update when you change folders?

does that state continue if you change folder? Yes and Drives
State only changes if I go to Single lister and back or Exit Opus
if you click on the status bar? Did not try will have to wait till it happens again
do the path fields still update when you change folders? Yes

For 12.18, we're going to go back to mixed_dpi_mitigations = False by default, since we still don't know why this is happening for at least two people and it doesn't make sense to create a new problem in the name of fixing an old one.

For 12.18.1 beta some time after that, there's another change I've made which may help when the mitigations are turned back on (and also assuming you're using Windows 10 1903 or above), but it's still just guesswork at the moment.

From looking at the double-source issue, one thing that might complicate things is script add-ins. Do you have any installed under Preferences / Toolbars / Scripts? Any which handle the OnSourceDestChange event? (If you right-click the heading above the list of scripts, and add the Details column, then scroll right, that gives you a way to check which events all of the scripts handle at once.)

Double-source issue
I have not had the Double-source happen on its own
But the other issue has happened on its own
Preferences / Toolbars / Scripts? OnSourceDestChange
I have 9 non have OnSourceDestChange in them
Could a script in a button have OnSourceDestChange in it and is the only way to see is to edit each button


Scripts in buttons: No need to worry about those. They can only do things when you click on them.

Still happening 12.18
Was renaming filename with Folder name this has not changed for a long time.
I highlight the folder name in the Left Lister
Click button command Clipboard COPYNAMES=nopaths REGEXP "(.+)\s*\s*( S)s*(\d)" "\1"
I them highlight the filename in the right lister and a rename button should appear but it did not that was when I noticed the extras in the bottom left of the screen and that both listers were Source
Preferences / Miscellaneous / Advanced [Troubleshooting]: mixed_dpi_mitigations False
Preferences / Display / Transition Animations All On
Jon asked When you say both windows are source, does that state continue if you click on the status bar? No they go back to Source and Destination

Could you explain that part in more detail? A rename button appears somewhere when you have files selected? Or is the button always there but changes from disabled to enabled?

Do you have any toolbars turning on and off when you change which side is source, or anything like that? Anything that moves parts of the window around when you change sides.

The button is hidden if no files are selected
The first line of the button is

Do you have any toolbars turning on and off when you change which side is source, or anything like that? Anything that moves parts of the window around when you change sides.


This only started with 12.17b4, What I was doing today has not changed since before 12.17b4
The time before when it happened I was copying from Right to Left with copy button

Copy AS

It may have happened before I highlighted the Folder name in the Left lister as I only noticed something wrong when I highlighted the filename in the Right lister and my Rename button did not appear in the Toolbar

Had already renamed about 10 files the button I may have used just before was either

Copy Move TO /DestPath1
Go "G:\TV Series 2019\TV Series 2019 OnGoing" openinleft
Select FIRST


Copy Move TO /DestPath1

But neither have been changed since along time before 12.17b4

We've made a change for 12.18.1 which restores the transition animation code to almost the same as before 12.17.4, and changes the way we detect mixed DPI. (We'll detect it on a display change, then cache the result, instead of testing for it each time we need to know if it's on or off. Those tests were the only thing added to the animation code in 12.17.4.)

12.18.1 was released today. Please test with that, without any config changes, for a while to see if the problem still happens.

If the problem comes back with 12.18.1, then please try turning off transition animations again to see if it still happens. (Maybe it isn't really related to them after all.)

Additionally, in 12.18.1 we have added a little utility which we'd like you to use to find out some information about the weird "location bar bits" in the bottom corner of the screen. Next time you see these, please click in the file display and press > to display the command field, and enter the following command:

Then press return.


This will display a little window with a crosshairs icon. You can grab that icon and drag it over windows to find out information about them.


Please drag the crosshairs over those mysterious location bars in the bottom-left corner of the screen. When the mouse is over the bars, release the left button (to stop the Window Info from updating any more), and then use the Copy button to copy the details to the clipboard and paste it in here.

Please do this for each of the different bars that appear (e.g. there were four in your last screenshot) in case the information is different.

@onedot3 Did you have a chance to try the Window Info utility?

Not yet as it has not happened since 12.18.1
