I'm running QT6 on both my linux lappies -- NO problems.
Before that, Qt4 & Qt5

Qt6 runs fine. Strange question.

objects are fine constructs. You can even initialize them with constructors.

I ran Lazarus with QT on a PowerPC Mac in 2006-2007. I think you need to be a bit more specific.

I am very curious to know which application (not necessarily from Lazarus) works better under Wayland than with last XLibre.

Wayland works poorly. Lazarus can't fix that.

Qt6 works great on Wayland. Any window position issues are Wayland issues, not Qt, not Freepascal/Lazarus and this is known for other programming languages too. Some frameworks work around that or simply advise XWayland to be installed as a dependency.

You must also understand the vision behind Wayland, which is "moving windows all over the place is not good design". I personally disagree as do many, so simply use XWayland.

I'm using QT (5 I think, maybe 6) on Ubuntu 24.04 and it works fine although I'm a very basic user.  I have Ubuntu set to "Ubuntu on XOrg" but don't know if that's important or not.
