Title: IDE in Linux, some bugs
Post by: pixel_ on December 03, 2021, 08:53:14 pm: One bug sometime is can't resize selected control in design and another is when I switch to another app in a taskbar and then tried back to Lazarus:
"Size range overflow in MainIDE.SendMoveSizeMessages: Width=1366, Height=-16."

I think those are the important things. I don't specifically recognise the problems you mention but I'm running KDE with stuff including the IDE typically compiled for gtk2... there's a possibility you've got some different combination or at least some different underlying libraries.

... sometime is can't resize selected control in design ...

Maybe this is the same as what that I experience:

Lazarus 2.2.0RC1-0, FPC 3.2.2, Lubuntu 20.10, LXQT 0.15.0, taskbar with autohide option.

Presumably the IDE is built for gtk2 and also using that as the default target.

/Might/ be worth trying with a different window manager and/or target if you can... I've been wrestling with something (non-Lazarus) over the last few days where an app wouldn't resize below a certain point which turned out to be WM-specific (needless to say, neither the app authors nor the distro maintainers admit the problem is theirs )-:

"Size range overflow in MainIDE.SendMoveSizeMessages: Width=1366, Height=-16."
That exception was added to spot a random bug which nobody could reproduce systematically.
Does it happen always for you?
It would help if you can get a proper debugger backtrace from it.
