Many osu! players have reported about these issues. The last working version is 22.5.2

Before 22.11.2 it would cause game crash or BSOD sometimes. Even on the latest as of now (22.11.2) OpenGL exclusive fullscreen still doesn't always work and the flicker issue is also still there.

@dipak Hi, can you please move this to OpenGL & Vulkan forum ? I have the same issue with exclusive fullscreen starting from 22.7.1 in minecraft and osu.

Hi @0ka ,

I have moved this post to the OpenGL forum. Also, I have whitelisted you and @Curi0 for the AMD Devgurus community. 

Thanks.

Dear Devs, in order not to force you to read the links above, I will write briefly: randomly after starting the game (osu or minecraft), the exclusive fullscreen may work correctly, or it may have vsync from dwm (like borderless window). if after start the exclusive fullscreen mode works fine, it can be broken with repeated fast switching between windowed and full-screen modes (F11 in minecraft or alt+enter in osu) or alt+tabs (only osu).

replacing atioglxx.dll in 22.11.2 from 22.6.1 fixes the issue but removes all performance improvements introduced in 22.7.1

Thanks for the above information. I have reported the issue to the OpenGL team. I will let you know if I get any update on this.

Thanks.

[dipak]

Just FYI, a bug ticket has been created to track this issue.

Thanks.

[0ka]

any progress? thx

[dipak]

As I can see from the internal issue tracking system, the issue is still under investigation. Once I get any update on this, I will notify you.

Thanks. 

[0ka]

can you add a video to the bug ticket?

[dipak]

If you have any demo video to demonstrate the issue, you can share the link here. I will notify the OpenGL team.

From the related bug ticket, it looks like the OpenGL team was unable to reproduce the issue locally.

Thanks.

in the video you can see "hello world" dwm overlay (https://github.com/rlybasic/DWM_Hook) which should not be visible in applications that use exclusive full screen mode, at the very beginning, when I switch modes slowly, it works correctly, but when i start switching very quickly between windowed and exclusive full screen mode (F11 key) exclusive full screen mode breaks and the dwm overlay becomes visible, this adds a lot of input lag.

instead of an overlay you can use the volume control through the keyboard buttons, volume control should not be visible in full screen mode. win + space layout changer also works.

same issue occurs in osu too, but there the game itself switches between modes often, and exclusive fullscreen breaks at start often, and good input lag is very important there.

if the problem still can't be reproduced, then this should help

[dipak]

Thanks for the above information and sharing the demo video. I will inform the OpenGL team about this video.

Thanks.

[0ka]

any progress? thx

[dipak]

I already informed the OpenGL team about the demo video and other information you shared in your previous post. I have not yet received any update from the OpenGL team. If I get any information on this, I will let you know.

Thanks.

[0ka]

nothing new?

[dipak]

I will check with the OpenGL team and let you know if I get any update on this.

Thanks.

Hi @0ka ,

As I have been informed, the OpenGL team was able to reproduce the issue (find their comments below) and they are still working on it. Once I get any further update on this, I will notify you.

"We were not able to reproduce the corruption shown in the video. But we can reproduce exclusive full screen mode breaks while switching very quickly between windowed and exclusive full screen mode (F11 key); verified with volume control through the keyboard buttons, volume control visible in full screen mode. win + space layout changer also works."

Thanks.

[0ka]

thank you! can you add more info to the bug ticket?
https://www.reddit.com/r/Amd/comments/yvyqc7/disabling_multiplane_overlay_mpo_fixed_all/ this makes exclusive fullscreen break less often somehow

[dipak]

Thanks for the above information. I have added this info to the bug ticket.

[0ka]

any news?

[dipak]

As I can see from the related bug ticket, the issue is still under investigation. 

Also, the OpenGL team informed that they still observed this issue after adding "Regkey OverlayTestMode with value 00000005" as mentioned in the following link.

Thanks.

Update:

The issue has been fixed internally.

Thanks.

[0ka]

no way!!! thanks amd

[dipak]

Hi @0ka , @Curi0 ,

Could you please check the issue with the latest driver (Adrenalin 23.7.1 ) and share your findings?

Thanks.

[Curi0]

Still occurs in osu! if I ALT-TAB alot quickly

[dipak]

Thanks for trying the latest driver and sharing your observation. I have informed the OpenGL team about this observation.

Thanks.

Just for reference, here is a related thread:  AMD later drivers have issues with OpenGL for fullscreen exclusive OpenGL only like osu!

Thanks.
