Graphical issues with FI: Grow FX and FI: Shrink FX

Hey y'all, long time user, first time poster.

I am having an issue with FI: Grow FX and FI: Shrink FX. Upon rendering a preview, Grow FX will be zoomed in unreasonably far, so far that all you can make out is a solid color. The inverse happens with Shrink FX, wherein the clip will become so small it does not even show. This issue can be corrected by changing any of the parameters in the Grow or Shrink effect controls, but it's a coin flip whether or not the issue returns when rendering previews. I've experimented several times and have not found any patterns - sometimes it works, sometimes it doesn't. 

Thankfully, the issue has not persisted through to exporting, but I attribute that to the fact that I've chosen to export with software encoding. I don't appear to have a software encoding option for previews though, so this bug is a huge pain for reviewing videos before export. 

Knowing that, I've tried reinstalling my nvidia drivers, to no avail. I've also tried clearing appdata\roaming\Adobe\common, and rendering in different preview file formats. No dice. I am running Premiere Pro 25.5, on Windows 11 10.0.26100, with a MSI RTX 5090 running studio driver version 581.57. This has been happening ever since I updated to the latest version of Premiere, and it affects all of the projects I've used it on so far. I've been searching on and off for days, and can not find anyone experiencing a similar issue. Any guidance would be greatly appreciated.
