Hi, I was using lazarus without problems, then installed LazPaint and
it look like this, as well any lazarus app (including the IDE), black
menus and strange font rendering.

I'm using a VM of Ubuntu 22.04 64.bit

The problem is that I do not know what is ubuntu default... I did a
quick search but the answer was inconclusive whether or not ubuntu
22.04 uses wayland by default. In case it is then you have your
answer. In that case there is usually a switch in the configuration
setting/setup that allows you to switch to xwayland (or x).

Because I constantly stumble on pages like this I can only assume that
wayland is the default server (and the page also shows you how to
switch   )

check export, i.e. type export in a terminal. You will see if wayland
is used or not. Look for this line:Code: Bash
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i declare -x
WAYLAND_DISPLAY="wayland-0" or similar.

Yes I found that line. So it is wayland.

FYI.
I encounter many problems related to Wayland (and also GTK2) on modern
Linux systems.
I have switched to QT5/QT6. Now, all apps run wonderful on any display
server.
