#79 problems with gfx_vsync=true

[kas1e]

While testing latest version of EUAE JIT, found that if in config file we have gfx_vsync=true , then once we run euae in window mode, and then switch to fullscreen: everything is black , and euae stop response. No freeze, no crash, just like intuition taken up by something. Or if we for example have gfx_vsync=true, and set in config to run in fullscreen from begining (via gfx_fullscreen_amiga=true), then all is black too.

Tested some previous versions (0.8.4) : there is no such problem. So it something which arise in light of latest changes probabaly.

If needs any more info , or more in -deep bug-report, i all in once anyone will have interest to have a look at this :)

Thanks !

Have you tried without JIT with version 1.0.0?
Also, could you please specify the screen type/resolution you are using?

Doing more tests, can say that amigfx version works fine. It is sdl version which cause that issue, and only with gfx_vsync=true. Its like something was changes in the SDLGFX driver which cause that .. (or wasn't changed which needs to be).

I also do all the tests without JIT, and it the same. So its not related to JIT , but to some changes done in general.

With amygfx version i through have 2 issues, but they for sure also not related to JIT , but general ones:

1). when you press ctrl+alt+s, it give you list of screenmodes to choice, while, with SDL version for example it ask nothing, it just choice the best mode to fit, and switch to it.

2). When you switch to fullscreen (i.e. choice mode, press ok), and then press "ctrl+alt+s" to swith back to window mode, it again bring you screenmode requester, like you switch not to window, but to another fullscreen :)

All tests done on x5k, with 1920x1080x32

Sounds like this is an issue with the SDL library I linked to the project. I am not an expert on SDL and I had no intention to support the SDL build. Maybe somebody else can create a new build which works better.

Is this the version you tried?

Is this the version you tried?

Yes. I also tried to build it myself with very latest sdl library (not on os4depot), and while it still give the same black screen issue, it at least give me ability to switch back to the window mode, while that one from os4depot didn't react on any keys after going to that black screen.

Strangely that 0.8.4 version works fine in that term. It can be even something about p96 changes ..I may try to put some printfs there and there, to see what going on, just to update ticket with more info, and maybe later it will help anyone who will worry about sdl build.

pd. Btw, as for amycgx build, is it worth to create bugreport about those issues when swith to fullscreen/backto window ?

I guess you could create a ticket, it never hurts to capture any findings. It is unlikely, that I am going to fix it, though. Somebody has to take over the ownership of the code base, I don't have much time to deal with it anymore. I might fix something JIT related, but any other change is out of the scope of the original project, I was just too enthusiastic with the improvements (what I regretted later).
