Text label shift - tracking down the root cause

I have an issue with my LabVIEW IDE. I am using LabVIEW 2025 Q3 Patch 4.

I have, since a month approximately, the situation where I regularly have a whole bunch of VIs with "changes" due to a text on the BD or FP shifting position by one pixel.

I have not edited these VIs, I have not edited any Typedefs being used and yet when I try to publish them internally, they get flagged as changed. I have code which allows me to differentiate between "LV saved the VI" changes and "actual" changes. This is an "actual" change.

Problem is, I have no idea what is contributing to this. Some things I think may play a role:

  • LabVIEW zoom: We have had issues with panel resizing where each move is calculated as a delta versus the old position, but when returning to the original position, there can often be a pixel shift due to rounding errors.
  • Remote Desktop: I connect via VPN to my office PC regularly. My home PC has 2 monitors, just like my Office PC. But one of them has a higher resolution and a higher DPI setting. I have, however, been doing this for years and never had this issue. IT started happening approximately 3-4 weeks ago.
  • Patch 4: No reason to think this might be involved, it just matches approximately on the timeline where this issue started appearing.

 

Does anyone have any experience with this?

No direct experience, but if memory serves I've heard of something similar before involving system fonts being slightly different on different computers. Are you using system fonts for the changed items?

 

Are you able to tell exactly when the changes happen? I.e., do they happen when you first open the project, the VI itself, etc.? I wonder if loading the front panel is causing something to shift around a little.

 

Also, the release notes for 2025 Q3 mention that some BD objects are now left-aligned:

  • Bundle by Name
  • Unbundle by Name
  • Unbundle/Bundle Elements on In Place Element Structure
  • Event Structure Data Nodes
  • Get Waveform Components
  • Build Waveform
  • Get Digital Waveform Components
  • Build Digital Waveform
  • Get Digital Data Components
  • Build Digital Data

 

Doesn't look from your screenshot like it was one of those items, but maybe if your text was "next to" one of those items?

This effect happens on the SAME computer.

 

Also, all of these VIs are pre-existing LV 2025 VIs. They've been edited and committed multiple times, tracking down exactly what's leading to it is the hard part. No system fonts, all fonts (in LV settings) set to Tahoma 13.

Perhaps worth a mention, we use a source distribution build spec to create out folder to "export". Don't see how that should be relevant, but you never know.

 

The only thing which sticks out is the remote desktop connection which can sometimes mess with system things. But I've been using remote desktop for years, never had this issue before. Unless something in Patch 4 for 2025 Q3 makes a difference.

 

Literally nothing else has changed in the VIs. Just the text location. I'm baffled.
