Came across a strange issue where I turned a forms borders off and found it would not centre.
Once I turned the borders back on, it would then centre.
I'm using QT5 on:

[System]
Gambas=3.16.1
Distribution=Linux Mint 20.1 Ulyssa
Desktop=CINNAMON

Can someone else confirm this - Wouldn't be the first time it's a 'me and my computer problem'

Edit: Using the Form parameters Border = false  then in the Form_Open procedure use Me.Centre.

[System]
Gambas=3.16.90 dbd2bb3a2 (master)
OperatingSystem=Linux
Kernel=5.10.36-2-MANJARO
Architecture=x86_64
Distribution=Manjaro Linux
Desktop=XFCE

sorry quin but can't confirm :-(

Not happening here..
Have you tried changing the qt5 theme to see if it's widget problem?
If persists i'd stick it on the bugtracker

 I installed cinnamon and now i get that bug.

Deffo a bugtracker report that.

You on there or want me to report it ?

I have reported this, but it's not going anywhere as Ben can't reproduce it. Bug report HERE. Video HERE.

 Thanks All.
The only other factor that I can think of that may have some baring on this is that I've run this same project at home on my standard computer with wide screen and there are no issues.
I'm currently on an old(ish) HP laptop so that may have something to do with it. (Graphics card?)

There are a few other 'weird' issues with this project graphics wise, so the device graphics may have something to do with it.
ie: I set a form to Full screen and it maximises to a size that is around 1cm on all sides of the current screen.

Will have to wait until I get back to my main computer to test again.
