I've found a bug (Access violation) with TBCFluentSlider when closing another app that use a sharedmemory segment from my main lazarus app, I get this error:

Access violation.
Press OK to ignore and risk data corruption.
Press Abort to kill the program.


I can't provide a sample sorry but I've spend an entire week tracking that problem thinking it was coming from my code.

The stack trace indicates that the access violation occurred during rendering operations, specifically while using the BGRABitmap library for antialiased drawing and rendering graphical controls. The issue seems related to drawing operations, possibly due to:

- Invalid or Uninitialized Objects:
        A TBGRABitmap object, or a similar rendering object, may not be initialized or may have been prematurely freed.

-Out-of-Bounds Drawing:
        Drawing functions like FillEllipseAntialias and others are called with coordinates or sizes that are outside the valid dimensions of the bitmap or control.

-Memory Corruption or Resource Management:
        Memory corruption could have occurred due to improper management of resources, such as failing to free or allocate properly.

Hi. Please send the bug report at bgrabitmap github.

And without a demo app we can't fix it... Try creating the bare minimum with your apps.

I do not have a github account sorry, if someone can post for me, thank you

I can report it tomorrow.

But without a demo is hard to fix...

@the_magik_mushroom

In order to be able to reproduce the bug and debug it, we need a sample project. It is understandable you would like to keep your code private. So we suggest to make a new little project that demonstrate the bug.

Hello, I'm developing an application using TBBCComboBox and found two issues (not sure if bugs or I'm doing something wrong):

Issue #1:

I have two TBCComboBox controls on a form (Form2) that is being shown from Form1 with .show (non modal). If I touch any of the combos (e.g. showing the dropdown list), when I close Form2, it happens that Form1 gets minimized or hidden (the user must find Form1 manually). This happens only after some kind of interaction with the combos. If I don't use any of them and close Form2, then Form1 remains on focus. It does not happen if I use a standard TComboBox control instead.  The issue happens on Windows but not on Linux (using QT6, don't know about GTK).


Issue #2:

Using the same scenario as issue #1 on Linux (QT6) when I click the combobox (dropdown list style), the dropdown list is shown behind the form containing the combo, so it can't be seen or clicked. This issue doesn't occur on Windows.


Platforms used:

-Windows 10
-Linux Debian (using QT6)
-FPP 3.2.2
-Lazarus 4.0RC2
-BGRA controls: 9.0.1.6
-BGRA bitmap: 11.6.2.0

Hello Mastropiero and thank you for the message. I've added the issue on GitHub (#231) and replied there.
