[BUG] Mouse clicks in menus are offset

[malventano]

Describe the bug

Mouse clicks within the menu are not properly aligned. The further to the right, the more the offset. I've represented the apparent zones in the boxes below. Note that to select proc the user must click far outside the window.

To Reproduce

Use a BTOP version new enough to have the 6 tabs in the menu (this did not occur with the older 5-tab versions).
Also note that mouse clicks register with correct alignment elsewhere within BTOP.

Expected behavior

Mouse clicks should register aligned with tabs.
