A small visual glitch with HW acceleration on XPSP3 (transparent borders are black) #15

I am using your latest 1.2.0.5059_withHWacceleration_build against Supermium 122 R6, on XPSP3 x86 with the setting: --use-angle=d3d9 --ignore-gpu-blocklist GPU: Ati Radeon HD4350

That introduces a small visual glitch around the tab preview, they are being drawn Observed result: "black"

instead of Expected result: "transparent"

This happens only when I do use the HW acceleration.

Is there a way to fix this, or any specific flag that I could use to turn off the HWaccel for just that specific feature, leaving the rest intact?

Furthermore: Can I send you a donation of 100$ via Paypal? if yes, please let me know your account.

IDA-RE-things commented 4 months ago

yes, I saw it. We should live with it for now. :) Same bug/issue happens on Win7, I have сhecked it. At least when I use "use-angle=d3d9" Without any of my changes and with original DLL and Win7 D3DCompiler_47. So it not depends on this HW acceleration restoration for XP. I will investigate this issue later. It's anywhere inside libGLESv2.dll, shaders code etc. This is not a priority yet, if you agree.

Ok, I am fine with that. I do agree that the --single-process issues are more important. I just hoped there would be a flag maybe where I could disable that specific usage of the acceleration in the meantime. Is it possible to send you 100$ as a thank-you for your recent outstanding work with the acceleration? Paypal?

Perhaps somewhere its possible to disable the DirectX call for this and do software rendering for that window frame, but finding this place is still difficult. And the best thing would be to find out how to correct the correct behavior. It will be for the future.

The paypal account has problem now for some unknown reason. I have not used it long time. And now I ascertain, whats happened, with their support service. Thank you for your willing to donate for the work have been done.

I have checked again on another Win7 machine. and on it all rendering works ok. Even in D3D9 mode. But here different card (NVidia GTX) with their drivers used. Thus, most likely this issue depends on the combination of system(OS) + DirectX driver + used Gfx card + driver for that card. And some (many of them) was blacklisted for that reason. Thus, resolutiuon of this will be for the future if no other things left :). We should say thanks that this works at all, because unsupported long time.

I definitely appreciate the current state already. For the record here is the drivers version I am using since ~13years for the GPU:

DirectX version 9.0c (4.09.0000.0904) I do think it is the latest for XP:

Nothing else was claimed, but just to give you a test-update: The issue does persist in "Supermium 124.0.6367.245 538" x86 + chrome-xpapi-adapter_x86.b5065-wD3D9accel.zip

IDA-RE-things commented 3 months ago

Yes, I have already tested it with Supermium v124. Nothing changed. And we are waiting for this issue will be fixed inside libGLESv2.dll or some other places. Now its Supermium Issue.

JoachimHenze commented 1 month ago

I do confirm that this bug has been fixed to perfection by https://github.com/win32ss/supermium/releases/tag/v124-r2 The bug is fixed with both: the stock shipped progwrp 1.1.5018 and also with ida-re-things 1.2.0.5067
