Hi Support,
We have detected an issue with the checkboxes in the AdvListView when having a 4k monitor.
Indeed, it can be hard to check the checkboxes.
Sometimes the click in the checkbox do nothing ... it depends on the position of the cursor inside the checkbox.
Delphi version: 12 update 2
TMS VCL UI version: 13.1.10
Best regards,
Nicolas
I retested this here but I could not see an issue.
Do you have more details?
This is a test on a 200% DPI screen:

We have it on several machines.
For example, i just reproduced it with the following configuration:
- Screen resolution : 3840 * 2160
- Scale : 150 %
- Windows 10
We also have it with a 200% 5k screen with Windows 11.
As explained, our application is built with delphi 12.2 and TMS VCL UI 13.1.10 ... so not the last one. I supposed you are testing with the last version. Could it have been fixed between version 13.1.10 and the last one ?
Best regards,
Nicolas
I test with the latest version TMS VCL UI Pack v13.5.0.0
I tested on 3840*2160 and Delphi 12.2 on Win 10, Win11 and I cannot see such problem.
I suggest to try with the latest version TMS VCL UI Pack v13.5.0.0 and if the problem somehow persists, send a sample source project with which we can reproduce the problem here.
I was now able to retest with the last version.
It seems slightly better but issue still occurs.
However, it only happens if ownerdraw is enabled.
With ownerdraw, checkbox has an older style and issue occurs.
Without ownerdraw, checkbox looks more modern and issue does not occur.
We checked this and applied further improvements for OwnerDraw = true.
Next update will address this.
