Operating System

Windows

What's the issue you encountered?

The GUI elements appears to be misaligned.
However, the mechanics such as click or drag is in the original correct position.
So for example, if I want to click the exit button, then I need to hover it to the top right corner instead of the rendered one.

How can the issue be reproduced?

Just run imhex-gui.exe

ImHex Version

1.33.2

ImHex Build Type

• Nightly or built from sources

Installation type

imhex-1.33.2-Windows-Portable-x86_64.zip

Additional context?

• OS: Windows 11 Pro for Workstations x64 23H2 v10.0.22631.3296
• CPU: Intel Core i3-2310M
• GPU: Intel HD Graphics 3000
• GPU Drivers: https://winraid.level1techs.com/t/get-your-intel-hd3000-sandy-bridge-windows-10-64bit-drivers-here/40044

Pay attention that with the unofficial drivers, it supports 100% up to OpenGL 3.1 instead of the default Microsoft GDI Generic renderer that is OpenGL 1.1.

Do you have any other solution other than the one in #442 ?

[Unknown78]

UPDATE

Even better solutions if this is your first portable installation/extraction

1. Run imhex-gui.exe, then Close Window or End Task of it from the Taskbar.
2. Go to the config directory and open settings.json
3. Find "hex.builtin.setting.interface.native_window_decorations" and change the false to true
4. Run imhex-gui.exe again.
5. Enjoy.

ImHex needs to be launched for the first time in order for it to create the settings.json file that we can edit.

I've just found the workaround.
It's rather annoying to find it, but hey it's working.

Extras > Settings > Interface > Window > Check Use OS Window Decorations
And then restart the program.
You don't need to click the exit button x and then click Yes to restart it within the program, just End Task within the Taskbar and then run it again shall suffice.

[Unknown78]

Will there be any negative impact if Use OS Window decorations is enabled?

[csBlueChip]

I can verify that Extras > Settings > Interface > Window > Check Use OS Window Decorations > Restart the program from the task bar solves the issue. Should probably make this default.

NB. When clicking the above options, ignore your mouse pointer, and watch for options to highlight when you are "near" the option.

It used to be auto disabled on Intel GPUs because it's exclusively an issue with their driver. I rather improve the detection than just having it turned off by default because it works without issues in almost all cases.

[Unknown78]

@WerWolv By auto disabled, do you mean that by default the value of native_window_decorations was true or false?

[kiraio-moe]

Thanks @Unknown78, it does the job 👍

[iTrooz]

IMO the solution would be to enable the option by default, simply because that means less things to handle for us (ImHex is a Hex editor, let the OS handle the window)

But I'm not against any other solution (e.g. better detection)

[WerWolv]

I think the first step to solving this would require getting some old laptop or something to reproduce the issue reliably. The reason why I never had a go at it anymore is because it just works on all my machines.

Up until a few versions ago I just disabled the custom window rendering for all Intel GPUs. This solves the issue but it's too broad of a condition. I've used ImHex on many computers that only had an Intel HD GPU without any issues so it only applies to either Intel HD GPUs of certain models or if there's some specific setting set in the driver I guess.
Until we either figure out the root cause of it or have a way to circumvent it somehow, I'd suggest we try to build a blacklist. As a start we should probably auto disable the setting if we detect a Intel HD GPU of Gen 6 or lower and from there on fine-tune until we find a pattern.

Of course this solution is far from perfect but I really want to keep the custom window rendering by default because in my opinion it makes the whole app look and feel a lot better

[Unknown78]

@WerWolv Just make a survey then?

I have i3-2310M with Intel HD 3000 with unofficial driver to support 100% OpenGL 3.1 in Windows 11

Which GPU do you have @csBlueChip @iTrooz @kiraio-moe @dmantisk?

[WerWolv]

Let's do that. I'll keep the issue pinned for the foreseeable future and will manually filter out reported GPUs until we find a better solution. For now, this here should "solve" the issue for new users: a991557
