Refresh and bookmark buttons are invisible until highlighted by the mouse. I don’t want to look for those buttons everytime I need to use them. Please help.

Thank you for letting us know, by any chance are you using any kind of extension in the browser ?
Also you can try disabling Hardware Acceleration in settings to see if this resolves the issue?
You’ll find this in Settings --> Additional Settings --> System --> Hardware Acceleration
Can you please tell us what version of the browser you have at this time ?
Hello @maka, apologies for the delay. Usually these issues are resolved after updating to the latest version, is this still an issue for you If so, please answer the questions below:
1 - What kind of device and OS do you have?
2 - Have you updated to the latest Brave version? If this is a desktop computer (found at brave://settings/help) to download the most recent one (https://brave.com/download/).
Regards.
