Scaling of forms not correct in Windows?

[stephanweber]

Hi,

I have now a new 4K monitor, and normally I am using a scale factor for Windows10 of 150%, so that the fonts are not becoming too small.

However, whatever I do in Lazarus, the scaling looks inconsistant. How can I influence this. The property checkbox " scaling" has no visible impact.

In detail: During construction, I see small fonts and all components looks as they should. But in execution the windo is larger, and many elements are now too large, so that they overlap.
I see this problem mainly in the main window.

Can anybody help?

Bye Stephan

Set the DesignTimePPI property of the form to 144 - in the object inspector

Thanks, but at least my my current projects I use 144 anyway (looks like the default because I never touched it).

Have you touched "force DPI scaling" option at designtime (in IDE options/form editor) ?

In case you haven't looked at it then more information can also be found at wiki High DPI

You should use the High DPI feature for 4k monitors.

What is your Lazarus version? Too old version do not support or not automatically enable LCLScaling.
