FFS V14.0 Configuration Edit Windows broken?

Posts: 63 · mdrmdr 18 Jan 2025, 11:14

Hi, since V14 its almost impossible for me to edit the lines in the include/exclude filter edit window. I can't see the cursor, the arrow keys do not work. If I click with the mouse cursor within a text, I can enter, somehow blind, characters. That's all.

Update: Seems to affect most/all config items. Cannot even change IP number of a copied configuration. Just went back to V13.9. All fine again.

Screenshot? Which operating system?

Posts: 63 · mdrmdr 19 Jan 2025, 11:18

It's on Windows 11 24H2 26100.2894 Windows Feature Experience Pack 1000.26100.36.0.

Just installed V14 for this test again:
I cannot make a reasonable screenshot, as just nothing happens when I open one of the config dialogs. If for example I want to change the IP of the "Online Storage - SFTP" edit dialog, I click on the IP address but do not see a cursor, cannot select it, backspace does not work. Typing does not work. Just nothing.

Back to V13.9:
Everything works again. As in every other program.

V14 here, I don't experience the issue. I recommend setting your OS theme to a default state and try again

Fair, but I have the issue with default theme (never changed) and only with FFS V14. All other programs and all previous FFS versions (did test now V13.8 and V13.9) work as expected.

A screenshot showing these graphical artifacts might still give a clue to gauge the kind of error we're dealing with.

As I said, you see no artifacts, just nothing, in V14 when trying to edit the fields. Therefore I made 2 small screen recordings. One with V13.9 and one with V14 doing exactly the same actions:

https://www.tr1.de/V14.mkv
https://www.tr1.de/V13.9.mkv

What I did:
• Double click IP address: V13.9 works. V14 no reaction and no visible sign that selection works
• Double click port: V13.9 works. V14 no reaction. Delete right "2" and enter it again. V13.9 works. V14 no reaction

Does that help?

The selection color in the text edit control is green. I'm not able to reproduce this in my Windows 11 system, even with accent colors enabled. What changes have you made to the OS theme that deviate from the default?

I have a 1:1 copy of my system in VMware for testing. In there, I did some theme related tests with FFS now.

Short: Same behavior as on real system, fully independent of theme settings. V13.9 works, V14 not.

Long: I have set the theme to standard theme (background image, colors, transparency). I played with almost all UI related settings. No change. In all cases, V14 does not work and V13.9 does.

But, from all my experience, It's more or less impossible that a theme setting causing this error. Especially if all other apps I use do work and all of your older versions of FFS I tested also work!

The question should be, what did change in the FFS code in regards to UI etc. from V13.9 to V14?

Whatever you've changed to turn the selection color green on your system is most likely what is triggering the issue (which doesn't mean it's the cause).

Posts: 63 · mdrmdr 20 Jan 2025, 17:01

Not necessarily, as it does also not work with somehow default settings. But the cause must be a change in FFS, as this was the only change on my system from working (FFS 13.8/13.9) to not working (FFS 14) ...

So you have no idea how you got the selection to be green?

Posts: 63 · mdrmdr 20 Jan 2025, 17:05

Come on, three posts above I told you that I set the UI to default, which uses blue. And blue also does not work. Same as red from another default theme. So the color for sure is not the problem. And why does V13.9 work with any UI setting?

And something important to add: FFS is an awesome and extremely useful piece of SW. I use it daily to sync all my Raspberry Pi's, NanoPi Neo's and my website with my main computer. I am very thankful that you develop and provide it. I'm sure this problem will be found and until then I'll use V13.9. Whatever you think is helpful in debugging etc., I'll support. E.g. does it make sense to analyze the input fields with WinSpy?

One suggestion I have is to use the {TAB} key to navigate to the text fields and see if anything changes. This might tell if there is an issue with the overlay itself, the entry fields, how FFS handles clicks, or something else

Posts: 63 · mdrmdr 20 Jan 2025, 22:09

Very strange. By tabbing through the fields, only a thin line is shown at the bottom of a field. So in the host/IP field. Just for fun I started typing "x". Suddenly they showed up right of the host name with a gap. After approx. 50x "x". See attachment 1. Then I resized the dialog. Now the gap between the host and the "x" was closed. See attachment 2. Backspace does not work. It seems that somehow fields are overlapping and disturbing each other.

Think I found it! The problem is caused by the display scaling factor. I use a 4K screen and must use 150%. Otherwise no text is readable. Set to 100%, problem gone. Back to 150%, problem there again. Does that help?

Posts: 4166 · xCSxXenon 20 Jan 2025, 22:53

Aha! I call that a smoking gun right there. I'm sure this will help Zenju dig deeper

Since it was late yesterday, I repeated the test. I can confirm the seen error on my system and on my system running in the VM (identical setup). 100% scaling works. >100% not.
BUT, I also tested it on the laptop of my wife. There it works regardless the scaling factor.
Nevertheless, I'm sure this is the right direction. What changed in this area between 13.9 and 14, as the old versions work like a charm?
