<p>Hi,</p>
<p>I've done some further investigation. <br>
</p>
<p>It seems there are 2 problems. <br>
</p>
<p>1) The update of the sketcher dimensions is slow. This also
occurs when using the FreeCAD Appimg files. But not with the
Flatpaks from FreeCAD. Both the stable as the beta edition.<br>
</p>
<p>2) I see some repetive residual ghosting after exiting the
sketcher, and doing some panning and zooming. This only occurs
when the part is semi transparent. This seems like a Wayland
problem. Because if I execute FreeCAD with: "QT_QPA_PLATFORM=xcb
freecad", the ghosting disappears.</p>
<p>I will try some more testing to see where the first problem comes
from. I have not much understanding of the Wayland problem, but a
workaround does exist.<br>
</p>
<p>best regards,<br>
Jelle<br>

Dear Maintainer,
Currently I'm modelling a fairly complex model in FreeCAD. I see significant
slowdown with the Debian package versus the Flatpak edition.
Observed:
Editing this file with the Debian native package. The Debian version is around
5 times slower when navigating and updating a moved dimension in a sketch takes
around a second.
Expected:
Both editions of FreeCAD having the same speed.
