AMD R3 Graphics Running Godot 4 in Compatibility Mode with Single Window Mode Off Gets Popped Windows Glitched Graphically (Fixed)

Godot version

Issue description

As the screenshots display, when I enter in Godot 4 in compatibility mode and pop a window or menu in the project manager, the popped show with glitches, which is annoying. Though the computer can run the manager in Vulkan mode (in which everything runs as usual and no glitches with graphics), it would break the entering of those who runs with GLES3 mode
I hope it could be fixed in 4.2 or future versions. :)

Steps to reproduce

1. Have a computer(a laptop is recommended) with the same APU mentioned in "System information"
2. Open Godot 4
3. In the project manager, click any button

I think it can be regarded as OpenGL Render problem like this:
#66458

[Lazy-Rabbit-2001]

I saw the bug got fixed in 4.1 dev1
but the project manager didn't, but anyways thanks for your hard work :D
I reopened this issue only for project manager

#79168 mentioned the crux of the bug: When a computer with an old AMD graphic card runs Godot 4 with single_window_mode false, the bug happens in the editor, too.
I think the project editor might uses separate window as default option, and that maybe adding a "project setting" with "single_window_mode" option could be better...
A temporary fix is to create a desktop shortcut and then set the param of target with "--single-window", which fixes the problem

So it shows that old AMD drivers doesn't support separate window well...

I think this should be forced automatically based on the GPU model name, rather than as a project setting. We can't assume project developers are aware of this particular bug.

#72831 could perhaps fix this issue as well, as AMD's Direct3D drivers are much better than the OpenGL ones on Windows.

Sorry, I didn't know there is an extra step to open ANGLE and thought it would automatically set on, and it fixes the problem now, thanks for your hard work and contribution to Godot :D

Can you confirm whether Godot 4.2 dev 6 (which is the first build to include ANGLE) works for you out of the box?
https://godotengine.org/article/dev-snapshot-godot-4-2-dev-6/

If not, we may want to keep this issue open and figure out a way to default to ANGLE instead of OpenGL drivers on systems like yours.

I am using 4.2 dev6 and have opened d3d11(ANGLE) render mode, and it does fix the problem. Very useful, except the first time i used this mode, it took much more time to load the editor than in normal opengl mode

Did you have to specify --rendering-driver opengl3_angle on the command line, or did it select ANGLE automatically?

opps, I input the command because it didn't trigger the mode on automatically...

@bruvzg @clayjohn Do you think it's possible for us to figure out heuristics for when to default to ANGLE?

[bruvzg]

Do you think it's possible for us to figure out heuristics for when to default to ANGLE?

If the driver reports that 3.3+ is supported (which seems to be true in this case), I guess the only way to do it would be to have a list of unsupported devices. It is already supported, but currently the list is empty by default, and I'm not sure how to populate it.

godot/main/main.cpp

Line 1773 in 42425ba

GLOBAL_DEF_RST(PropertyInfo(Variant::ARRAY, "rendering/gl_compatibility/force_angle_on_devices", PROPERTY_HINT_ARRAY_TYPE, vformat("%s/%s:%s", Variant::DICTIONARY, PROPERTY_HINT_NONE, String())), Array());

Kinda sorta related to that old bug/issue proposal about having a blacklist of badly behaving GPUs?

[Lazy-Rabbit-2001]

closed for the bug can be fixed by opengl3-angle(d3d11), and the extending bug of not automatically switching to ANGLE when opening from .exe without any parameters will be mentioned in a new issue post #84517
Anyways, thanks for your hard work on Godot

Hi. I am having this problem. Can you explain me how to fix it? Thank you
