artifacts in redream emulator (regression in Windows GL driver)

Hi all,

I'm the author of the Sega Dreamcast emulator redream (https://redream.io).

For years on Linux we were plagued with a driver issue that resulted in artifacts due to an invalid GLSL optimization (see https://gitlab.freedesktop.org/mesa/mesa/-/issues/2253 for more details).

This was thankfully fixed in May of last year, however then in August we started getting bug reports on Windows from users who'd updated their drivers of artifacts that looked suspiciously similar.

I've attached photos of the artifacts on Windows. I unfortunately don't have a frame capture to provide, but if that'd help push to get this investigated I can try and work with someone to provide one.amd_windows_artifacts0.pngamd_windows_artifacts1.jpg

It's an AMD issue for sure. I swapped out for my nvidea rtx3090 and problem was resolved. AMD caused so many issues with many older Clancy games such as rainbow 6. It just sucks

Sorry, what does this mean?

Being the software Dev,, it may be better to report the issue in Developers section.

Just a guess, it could be related to the opengl drivers overhaul?

I can confirm the same problem with my RX 6600xt running windows 11 with the latest AMD Adrenalin Drivers.

Tested a few hours ago, same problem. Flickering screen with VSYNC activated and artifacts all over the screen like the screenshots posted above. I have a RX6700XT with the latest adrenalin drivers and windows 11.

I have the same issue, had to downgrade to an earlier driver to fix it.

Well, **bleep**...

 

I was all set to buy a 7900XTX until I came across this thread. Thank you, inolen, for saving me a return.

Dreamcast emulation is one of the primary functions of my gaming pc. Given how long it took AMD to fix this issue on Linux, I guess I should err on the side of caution and buy a 4080 instead.

Just chiming in to show that this is a pretty big problem.  Same thing happens to me.  7900XTX.

Haven't been able to use the emu for quite sometime now, updated to driver 23.2.1 and the issue remains...

RX 6800, 23.2.1 driver, the issue still remains.

Same issue here on an RX 6800 XT.  These drivers absolutely cause this weird artifacting.

Adrenalin 23.2.1 still not fixed.

Driver 23.2.2, still has issue with 7900XTX

This regression still persists on Windows 11, driver Adrenalin 23.2.2 (fresh install of windows btw), with an AMD RX 6750 XT and has been since day 1 of me purchasing my AMD card 2 months back. Was flawless on my previous GeForce. Heck, the stuff even runs on Intel integrated sh*t. By the way, I tried the Linux version of the emulator with amdgpu and there, it was flawless. Which is kinda infuriating, because it means that AMD themselves f**ked up their driver on Windows.

Artifacts still occurring. Driver 23.3.1 released 3/5/2023 on 7900XTX, and most likely on all of the other cards.  Please sound off for other cards that are impacted by this.

Regression still persists in driver 23.3.1, RX 6750 XT, Windows 11. Meanwhile, the emulator (latest build) works PERFECTLY with amdgpu driver (Manjaro, latest stable kernel) on Linux.

So, does the OP not post the progress on their website?

He has been in contact with AMD Devs.

What progress? The issue persists...

https://community.amd.com/t5/opengl-vulkan/artifacts-in-redream-emulator-regression-in-windows-gl-dr...  Looks like Inolen did in fact have a ticket opened and the GL Driver team at AMD fixed this interally. As of 3 weeks ago the person who advised from AMD this was fixed said, "the fix is likely to get promoted to the public driver soon." That was around March 7, 2023.
