I found a way to fix it, i uninstalled Opera and installed a new theme with the default font colors and uninstalled that.
Then i just installed Opera again and the colors are back to black, thanks for the help.

Yes, i'm now using Windows default theme, with modified wallpapers.

Here's a screenshot so you can see what it looks like for me: screenshot

I recently installed a theme on my Windows 10, and it change the text color in Opera only.
I have uninstalled the theme since then, and restarted my pc.

I've been looking around on the internet for a while to see if i could find a way to change it back, but could only find solutions for older versions of Opera.

I checked the font options in the Settings, and there's no color options.

So this is my last resort, i don't want to install plugins or anything like that just to change the font color.

I fixed it after uninstalling Opera many times and creating a new Sync account.

Well as the title says, my bookmarks positions change whenever i close Opera.

They return to the same position everytime, one i've never used before.
It's been bugging me for a while now and i don't know how to fix it, it started when i imported my bookmarks from a html file from Chrome.

I placed the bookmarks in the order i use in my other browsers, but they just return when i close Opera.

Sorry if it's described it bad, i just don't know how else to.

So if anyone got any ideas, please let me know.

Information:

Opera version: 38.0.2220.31
Windows 10 Pro (64 bit)
I don't use any extensions.

I know, i was just hoping someone knew a way to "fix" it, since it was kind of in the same category as this thread.

I even know why Firefox doesn't do it, but i can't find a way to make Opera do the same, i really find it ashame since i think Opera is a better all-around browser for me.

Anyway, sorry if if i asked in the wrong place, it was not intended.

I have a similar problem, even though i think i've found what courses the problem in my case.

The problem i have is because i have 2 monitors with 2 separate Opera windows, and when i watch a Youtube video in full screen on my left monitor, and try to do anything else in the other browser window on the other monitor, the task bar pops up over the video.

Which means either Opera or Windows thinks that i select another application instead of the same browser, just another window.

I think that's because instead of doing what Firefox does, which is "extending" the browser window instead of adding a new window. Opera just adds a new window which i think Windows registers as another application. Screenshot by Lightshot

I don't know how else to describe my problem, i use Windows 10 Pro 64 bit, and Opera version 38.0.2220.31

I have the same problem with Chrome by the way.
