Histogram window update becomes very slow in log mode
Posted: Fri Apr 12, 2024 8:13 pm
Hi Folks
I encountered an issue today where the histogram window contents update very slowly with logarithmic checked.
The histogram window is responsive without logarithmic checked, but any operations such as scrolling in horizontal zoom mode or moving/resizing the window slow down dramatically with logarithmic checked, even causing the program to become unresponsive on occasion.
Note- the problem occurs on one of my two laptops. Details as follows:
Both systems running Windows 11 home edition.
Sharpcap version 4.1.12025.0, although the same problem shows with previous 4.1 version
The problem unit is an ACER Swift Edge, AMD Ryzen 2.7 Ghz 8 physical/16 logical core. 16G RAM
Display resolution 3840X1050
The unit without the problem is a Dell Inspiron, Intel I5 1.3 Ghz 10 physical/12 logical core. 16G RAM
Display resolution 1920x1080
Here is a log- test camera 1, open histogram, check horizontal zoom, scroll horizontally- window updates normally
Check logarithmic, scroll horizontally- window contents refresh VERY slowly.
Any suggestions would be welcome.
