I'm running Excel 2007 using a PlayOnLinux virtual drive (wine 6.18) and while everything works great, some textboxes are glitchy and unusable:

What could be causing this? Here is my setup:
OS: Linux Mint 20.1 (amd64 kernel 5.13.0-22)
Wine: 6.84 non-amd64 and no dx9 overrides (so it uses OpenGL, but I have no idea if Office itself uses OpenGL or DX9)
GPU: GT 730 (nvidia driver 470.86)
CPU: Ryzen 5 2400g
Also, a log: Thanks!
