Powercord text background bug

[Davoleo]

I think this has been introduced in the last few commits Seems to happen when text is on a background color that is different from the normal theme background

I can test more things if needed

As a side note this doesn't occur in normal discord settings buttons, only in powercord ones for some reasons but it also happens on screen sharing and video buttons when in a voice channel

Same issue on normal discord with BeautifulDiscord.
