Visual C++ Assertion Failed! GL_NO_ERROR (video and audio works but it's impossibile to use xemu)

[denosys]

Bug Description

This popup message appears at startup (debug version) :

VisualC++ Runtime Library
Assertion failed!
Program: C:\Users\win7user\Documents\XEMU\xemu.exe
File:../ui/xemu.c
Line:1551
Expression:glGetError() == GL_NO_ERROR

Expected Behavior

No assertion failed message

xemu Version

0.7.132 (debug)

System Information

CPU: AMD A8-3870 APU with Radeon(tm) HD Graphics
OS_Version: Windows 7 Enterprise Service Pack 1
GL_VENDOR: ATI Technologies Inc.
GL_RENDERER: AMD Radeon HD 6550D
GL_VERSION: 4.0.12874 Core Profile Context 14.100.0.0
GL_SHADING_LANGUAGE_VERSION: 4.30

Additional Context

If I keep pressing "ignore" I can advance correctly in the startup procedure. I can view the animation (obviously jerky because the video animation only advances by steps every time I press it "ignore") and I also hear the sound in the background.

Unfortunately, it's not possible to proceed further and for example click the menu options (try to access the menus is impossible due to the assertion failed window always in the foreground). I also attach some screenshots where you can see that the video signal is present and works .The integrated GPU supports OpenGL 4 as can be seen from the log.txt.

what would be really interesting would be the possibility of have a test version that only bypasses and ignore this message because from what I can see the system would work perfectly if this message didn't appear. The program probably doesn't recognize something and thinks there is a problem but I repeat the video and audio should work perfectly if this message didn't appear. The normal xemu version crash precisely because of this and in fact I ran the debug version to understand the reason for this crash.

Is it possible to do something to fix this bug? It seems an OpenGL (but I have an OpenGL4 iGPU and in fact I have the video as you can see from the screenshots). If it were possible to create a test version that ignores this message to carry out a test I am available to try it. It seems like a strange bug to me since video and audio seem to work but with this popup always in the foreground I can't do nothing and so it's impossible to use xemu. Maybe you just need to ignore something to make the emulator work perfectly even in a system with a similar configuration to mine.

It seems related to the call sdl2_gl_refresh(&sdl2_console[0].dcl) in the while (1) cicle in ui/xemu.c It seems an OpenGL error and sdl2_gl_refresh being called continuously this error occurs continuously. Maybe a change in the code would be useful to print the error code returned by glGetError() before the assertion.

Thanks to the developers of this fantastic xbox emulator for their work and everyone who can help with this bug. THANKS!
