The side bar 'Rules' button causes disproportionately high CPU usage when visible.
Picture for clarity
Observations:
• Found on desktop version of Torn (no info on mobile version)
• OS Windows 10 Pro
• Bug persists through software and driver updates
• Bug present in a fresh install of latest Opera without extensions as well as an older install with extensions and customized settings
• Bug present in a fresh install of latest Firefox
• Bug not present on MS Edge
• Performance on Opera returns to normal when the side bar Rules-button is deleted / hidden, with some exceptions such as pages where CPU usage is abnormally high for reasons that are possibly independent from this issue (e.g. the "Travel page" where deleting or hiding the button does little or nothing while the CPU usage remains higher than normal)
I deleted the Rules-button in Dark Mode in Opera and the CPU usage immediately returned to normal. Ctrl+Z and it goes back up.
In Opera the performance decrease stays at a consistent 13%. Disabling Dark mode in Opera also returns the performance to normal.
Interestingly, the same problem is present on a fresh install of Firefox, but it doesn't seem to be entirely restricted to Dark Mode, the performance impact is less severe, and the CPU usage appears to fluctuate; it peaks at 13% but then drops to 1–6% when the button is visible. It is also immediately reduced when the Rules-button is deleted.
Edit: updated format and findings
