screenshot of gap between taskbar and maximized window

SUMMARY
For panel height 42, there is gap between task bar panel and maximized window, so that colors of wallpaper can be seen. 

STEPS TO REPRODUCE
1. With panel at the bottom (all default, floating), set height to 42
2. Set some colorful background on your desktop to better see the issue
3. Open some dark program, i.e. Konsole, and maximize it

OBSERVED RESULT
There is 1px gap between taskbar and maximized window, wallpaper colors visible

EXPECTED RESULT
Bottom of maximized window should snap to taskbar without gap

I'm assuming Konsole is not being forced to run under XWayland, right? If it is, then this is Bug 459373. If not, then this is Bug 480171. I'll be presumptuous and guess Konsole is running as a native Wayland app, and mark this as a duplicate of Bug 480171.

I am not using wayland at all. I don't even have nvidia KMS enabled (which is must for wayland afaik)
Comment 5 Nate Graham 2024-10-03 21:43:16 UTC
Oh, I missed that, sorry, if you're not using Wayland, then it's Bug 423390.
