Transparency setting not working

[LittleHendrix]

Describe the bug

Same issue as reported in #6545

I have tried running kitty cat and it works as expected (see attached).

kitty cat renders transparency as expected. However, it's not working when I load kitty normally, and I can see that it's trying to apply transparency as I can see the transparent gaps (padding) around the terminal window. But the main area is completely opaque.

On older versions of kitty, run kitty --debug-config instead

that will mean your shell rc files are changing the background color. Bisect them to find the culprit.

Thank you for the quick reply 👍

@LittleHendrix where you able to identify the specific issue?

[sherloach]

same here! did you find any solutions please? @LittleHendrix @Bretton-K-Scarbrough

@Bretton-K-Scarbrough @sherloach ok guys, what I had done to make this working in the end, was to reboot the OS. I've tried reloading the config inside kitty, as well as restarting kitty. But neither had worked. And I didn't change any settings in the end, as it looked correct. So, after a fresh reboot, I started kitty, and then the transparency kicked in.

[sherloach]

yes, it worked. Thanks! @LittleHendrix

Didn't believe it would work, but rebooted and sure enough. Would love to know why. Regardless, thank you!
