I'll check that. Are you using OpenCV 4.x?

[chris-shenzhen-china]

i think the issue is always there both opencv 4.x and opencv3.4.6,

Ok, thanks for the info. I think I've identified the problem. I'll make a patch soon.

Good evening Fernando !

I stumbled also on this problem, using opencv 4. The patch below seems to do the trick:

cvui.h line 2089; add the line "aOverlay = cv::Mat..."

void window(cvui_block_t& theBlock, cv::Rect& theTitleBar, cv::Rect& theContent, const cv::String& theTitle) {
  bool aTransparecy = false;
  double aAlpha = 0.3;
  // Replace the line "cv::Mat aOverlay;" by this:
  cv::Mat aOverlay = cv::Mat(theBlock.where.size(), theBlock.where.type());

Thanks, Pascal! I'll work on the fix using your patch.

That must be some sort of record (1 year of "I'll work on it") 😄

As the maintainer of the project, I honestly apologize for this. I work on cvui during my free time, which has been quite limited. For those monitoring it, cvui is not abandoned, just under-maintained.
