The problem is linked to display scale setting of the primary display. If you close the sensor panel and Aida64, set the scaling to 100% and reopen Aida64 and the sensor panel it will be the correctly resolution of 600x1024. Aida64 definitely needs an option to disable resolution scaling for the sensor panel
There's a workaround to this by scaling different values in the file down. For example in my case I have a scaling of 150% meaning if I multiply all the values "ITMX", "ITMY", "TXTSIZ", "BARWID", "BARHEI", "WID" & "HEI" by 0,666 and change the resolution from 1536x900 back to 1024x600 I get every template looking the way it should
