Does it include any theme/appearance changes? I just updated mine to 4.6.1 and I can't go back to that previous white theme! In the preferences there are two color theme but none of them makes it look like before. Both are in blackish tone.
Your computer is on dark mode is the reason. Electrum need to have the third one which is 'system default'. So I will say it is a bug.
If you want the white theme, you will need to change your system mode from dark to light mode. So you will be able to use either the white or the dark theme on Electrum. But if the system mode is set to dark mode, the light theme on Electrum is the dark theme also, it will not change. I like the dark mode because that has been what I am using since many years ago.
I noticed this issue on version 4.6.0 also before I updated.
If you want to change your system mode, go to 'personification' if you are using Windows. I am using Windows 11.
Thanks mate for clarifying the reason. To be honest, I got worried for a second there because I kept changing from dark to light but it remained dark despite everything. I thought I installed a compromised version of electrum.
Yeah, I just checked my personalized setting and the system was in dark mode.
Older version didn't have this issue. I was in version 4.5.x something and even with system dark theme, electrum was in white theme. But after installing the update, it went fully dark.
