PureBasic Forums - English

I'm having trouble with OpenScreen() and WindowedScreens(): Flipbuffers() causes an memory error. (tested with the original "WindowedScreen" PB Example). I reinstalled PB5.71 and also disabled my antivir program but that's not causing the issue.

Greetings A.D.

*please read posting #4

No problems here with PB v571 LTS x64 on latest Windows 10 Pro x64 v1903 build 18362.295.
Using Windowed Screen example file.

could somebody do me a favor and compile the Windowed Screen Example and upload it for me, please!

i investigated a little bit more and i found out that the issue occurs only when i am using Purebasic5.71_x64. I installed the x86 version and everything works fine. Maybe it's a PureBasic5.71_x64 LTS bug but not for sure.

the compiler tells me "invalid memory access (read error at adress 420167560) with FlipBuffers() command.

*update: when i choose as subsystem OpenGL with PB5.71_x64 the example is running without any error.... I checked DirectX with dxdiag.exe and it tells me there are no problems. this is weird, isn't it?

It's weird you did not read my reply

i read your post, skywalk. The question is what could be broken on my system so that x64 won't work properly but x86 does and how to repair it.

I was referring to your claim that it might be an x64 PB bug after I said the code worked for me.
I will post an exe of the example for you to try when I am near a computer.

yes, i also think something is messed up with my DirectX after the update to 1903, but maybe the problem is related to v1903, purebasic and different hardware setups, who knows

thx skywalk, your compilation is not running correctly on my system. I would be grateful, if anybody knows how to fix this so i don't need to setup a new win installation. When running the exe Windows reports an error message "werfault.exe" in combination with MS Visual C++ 2017 Redistributable.

I have a hard time believing that the problem is related to Purebasic.
Have you tried turning off werfault.exe to see if the problem persists?

yes, i tried this...this is what i already have done:

- sfc /scannow
- dism
- chdksk
- memory test (100% ok)
- checked DX with DXDiag.exe (100%)
- shutdown of WerFault-Service in System Control
- reinstalled Visual C++ 2015/2017 Redistributable
- reinstalled Purebasic
- reinstalled nvidia driver with DDU.exe
- virus scan (no infections) / disabled antivirus app

Do you have multiple monitors or recording/profiling software that
could automatically hook into the renderer?

A.D. , install DX9 again, look my post here:
viewtopic.php?f=7&t=73083#p538455
since the ALAN does not reply i suppose it works.

unfortunately installing them didn't fix the issue
