I configure PGenerator 1.4 with Calibration Patches set to Custom and Patch Area set to 9.65, with Resolution 3840x2160 23.98 Hz, and capture the resulting on-screen window size. I then set Calibration Patches to Off, and then back to Custom, and the new on-screen window size is now smaller than before, but the Patch Area is still displayed as 9.65. If I manually enter 9.65 again, the window size increases back to its original size. This is with the 1.0.0.1582 Beta; I don't know if the same is true in earlier releases.

Unable to replicate.
And you can also check ColourSpace operation by having the floating patch window active and set to full screen.
It will display the same patch size as set within Settings as being used by PGen.
So I guess could be a PGen issue of some kind?

I get similar results with a VideoForge Pro. I've done digital captures of the output of both devices. Consistently repeatable.

PGenerator initial window: x=1324 y=745 w=1193 h=671 (area 9.65113)
PGenerater after off/on cycle: x=1344 y=756 w=1152 h=648 (area 9 exactly)

VFPro initial window: x=1324 y=744 w=1192 h=672 (area 9.65741)
VFPro after off/on cycle: x=1344 y=756 w=1152 h=648 (area 9 exactly)

This is so obviously a bug. It appears the fractional part of the Patch Area value is effectively always discarded when switching to Off and then back to Custom.

Can you define a simple way to replicate, without the apparently unnecessary resolution and frequency info, as if we can replicate we can define the cause?
The simpler the instructions to replicate, the easier it will be to define if there is a bug, or not.

I thought I provided that in the first post. I provided some details since I didn't know what's significant to the bug and what isn't. (It's not my job to determine all possible settings permutations where the bug occurs.)

1. Start ColourSpace.
2. Connect to PGenerator. (I'm using 1.4.)
3. Pick whatever Resolution you want.
4. Set Calibration Patches to Custom.
5. Set Patch Area to 9.65.
6. Display a patch and note/measure/capture the size.
7. Set Calibration Patches to Off.
8. Set Calibration Patches to Custom.
9. Note/measure/capture that the patch displayed is smaller than before.
10. Retype 9.65 into the Patch Area box.
11. Note/measure/capture that the patch area gets larger as soon as you hit Enter.

Basically, if, after having set custom, you retype 9.65 I can note a slightly bigger patch on the display.
I have done some tracing and you can see CS sends different window size information when setting custom (step 1) and then when retyping 9.65 (step 2).


I have also noted, that if I instead use automatic, with custom diag and area = 9.65, I get exactly the same values I have for the above second step.
