I can't test on mac (I've no mac).

I just tested with this file on windows (22h2) and linux (mint 21.something) with my machine (RTX 3070):

MakeSceenShotTest.zip

And It seemed to work.

A previous issue on linux related to MakeScreenShot was fixed here: https://github.com/UPBGE/upbge/commit/ee50a07006027365ff3da3806a29448f2d73723e

Could you provide more infos on your OS, Hardware (GPU/CPU...), is it using metal backend, exact steps to reproduce the issue, upbge versions tested (you need to test last version based on blender 3.6 alpha) please? Thanks. (https://github.com/UPBGE/upbge/wiki/Report-a-bug-guide)

yes, i have made a simple test file here: https://github.com/sevi78/UPBGE-Tests/tree/main/VideoTextureTest i am using:

UPBGE 0.30.0 hash2df03652494 Branch:upbge-v0.3-release from https://upbge.org/#/

on:

MacBook Pro (Retina, 15-inch, Mid 2014) 2.2 GHz Intel Core i7 16 GB 1600 MHz DDR3 Macintosh HD Intel Iris Pro 1536 MB

I am using 2 Monitors, but have testet also without second monitor.

There is nothign to see in console, any bugs or problems from upbge:

Blender Game Engine Started
Blender Game Engine Finished
Debug: 1660, 992
rcti: : xmin 0, xmax 1659, ymin 613, ymax 1604 (1659x991)

Blender Game Engine Started
Blender Game Engine Finished

i am pretty shure, it has something to do with my old system

Is there any repo to download the latest 3.6 Version---- i am not shure to manage to build it my own... I testet now your file aswell, only black bar at the bottom. I will make a test now on windows and give you answer if it runs.

thanks.

You can download development versions from here (there is a link on upbge website)

I bet the bug you mention is fixed with the commit I mentionned... In this case you can try to find a development version which works for you and use it... (Generally, builds which are just a bit before blender release dates can work better)

i have testet now on osx: could not install any of the builds because my system is too old. BUT: i testet aswell on Windows 10, where UPBGE 0.3.0 didnt work, but UPBGE 0.36.0 works fine. So i would say, thats fine. Thanks for your time

Ok, I think I can close this report as the bug has been fixed normally. Sorry that you didn't find any build working for your system with this bug fixed. upbge is still opensources and can be compiled from sources, but it requires a bit of experience to build blender/upbge, and more experience to build old versions of blender/upbge.

There's this guide for Blender: https://wiki.blender.org/wiki/Building_Blender/Mac but it's only to build the last available blender master, not an old one (which would need to have the right version of precompiled libraries, the right "checkout"/date in blender/upbge git sources and eventually other environment settings)
