Voukoder Pro 3 causes UI text corruption in Vegas 23 when using a comma-decimal locale Regional Format in Windows

I'm on Vegas 23 build 356. Every time I skip a frame or perform any action, another "p" is added below the preview shown in the screenshot above, where it should be displaying stats like frame rate instead. Skipping to a different frame adds exactly 3 extra "p" every time. Eventually it exceeds the bounding box for the text there and vanishes.

In Project Preferences, the "Pixel aspect ratio" and "Frame rate" fields are pulling the bottom string from the Template drop-down menu (HDV 1080-24p 1440x1080), and those templates no longer display their frame rates but in some places display Chinese characters instead:





Text corruption exists in other places throughout Vegas. Eventually the program crashes because of it. Uninstalling Voukoder Pro fixes the issue. I have tried reinstalling both it and Vegas as well as removing all cached files and settings, didn't work.

I rolled back to 302 but the issue persists.

Root cause found: Windows Regional format (decimal comma) breaks VEGAS/Voukoder UI/template metadata
I had severe UI corruption in VEGAS Pro 23 build 302 (template FPS values missing/garbled, random characters, fields showing wrong strings, preview UI text accumulating, etc.) that persisted across reinstall, cache resets, sfc /scannow, driver changes, removal of other plugins, even clean boot.

Fix: Changing Windows Settings -> Time & language -> Language & region -> Regional format from a comma-decimal locale (e.g., English (Denmark)) to a dot-decimal locale (e.g., English (United States)) immediately resolved the issue.

This strongly suggests a locale parsing/formatting bug (comma vs dot decimal) affecting Voukoder Pro plugin's parsing. Reproducible on my system; persists until regional format is changed (or until Voukoder Pro is uninstalled.)

Request: handle locale-aware numeric parsing/serialization (use invariant culture or explicit locale)

(and kindly grant me a Voukoder Pro key since I had to spend my trial solving this bug. My trial key became invalid when I did every possible thing to diagnose the issue, probably when I deleted appdata folders.)

As Marko65 noted this issue was a known issue in VEGAS Pro, not in Voukoder Pro, but I can give you ...

• Allow you to re-register for the trial version, so you have 14 days more to test
• A discount code about 10 EUR

I would like that.

Marko65 noted a different issue than mine on build 356, and I'm now on build 302 where my issue still happens, it was unrelated to the build. Since this issue only appears when combined with the Voukoder Pro plugin and not any other plugins, it would be odd if it was Vegas that is at fault, but I suppose it's possible. It does seem more likely that the Voukoder Pro plugin doesn't have locale-aware numeric parsing in some place, if it was Vegas then it should occur when I set my system's decimal character to comma in Regional Format regardless of whether Voukoder Pro is installed or not.

Perhaps you have not had your coffee yet? It is very early.

What was your language/country setting when this has happened?

English (Denmark). Swapping it to English (United States) or simply changing the decimal character from comma to dot fixes the issue.
