Windows 10 can't handle big windows...?

[lexikos]

On my Windows 10 (version 1607) system, this code crashes the desktop window manager, kills my entire login session and kicks me back to the login screen:

Code: Select all

Gui, Show, w32767 h32767

At first I thought it was a driver problem, because after I logged back in Windows told me the driver failed to start. However, re-running the code while the video driver is disabled gives the same result.

Does anyone else have this problem? (I'd suggest closing any programs before testing...)

It does not cause any problem on my Windows 7 VM.

I'm not sure how any of that is relevant. I don't think it's indicative of anything other than what I already knew because it was blatantly obvious: the session was terminated. (Assuming it crashed for you too, and that was the debug output.)

Session 7 is terminating after waiting for 0 ms;

Was it a long wait?

[jNizM]

Was it a long wait?

Nope
Double click -> black screen -> wait 5 sec's -> relog

Tested on Win10 Ent Version 1607 (Build 14393.51)

Crashes also with 32766.. others not tested

[lexikos]

I was referring to the 0ms wait.

[just me]

I'm still on Win 10 Pro x64 build 10240 here (because later versions refuse to run on my machine). The scripts doesn't crash, but the window isn't visible. The window switcher shows some odd-looking AHK GUI preview, but cannot bring it up visibly. It's capturing mouse and keyboard input, though.

[joedf]

Very weird... I'm currently running a full scan so I won't be testing this anytime soon. However, does it crash when you grow the window gradually?

[Elesar]

Windows 10 Pro v1607 here. Confirmed that this crashes my system as well. I don't get kicked to login screen, but it does crash my drivers and kicks me down to a single monitor. I don't have any issue with windows at my total resolution, or even a few hundred pixels over my total res.

Currently running 6 1920x1080 monitors in a 3x2 layout for a res of 5760x2160. Tested up to 6000x3000 without issue so far.

[joedf]

So, Ive tested it. It freeze/slows my explorer.exe ie taskbar, desktop, etc. However, I was able to run task manager to kill the script.
Definitely something weird going on. I have a feeling Win10 has lots of problem with their new "explorer.exe". My login screen would occasionally freeze.
Could be unrelated. Either way, it's weird stuff.

How big windows are expected to work?

[lexikos]

It's not about whether the window works, just how badly the system handles it.

I don't want to make big windows; I only encountered this problem because a combination of AutoHotkey bugs (most of which were fixed in v1.1.24.02) caused the window to be resized to (up to) 32768 x 32768 under specific conditions (which likely never happen in the real world). I was totally confused when I ran a simple Gui test script (which did not use any hard-coded coordinates) and got kicked back to the login screen.

The number comes from the minimum coordinates possible for a window, which seem to be -32768,-32768.

I see.
As you said, Gui, Show, w32767 h32767 doesn't seem to make trouble on win7. For me, the window just doesn't show. However, if I half the width and height, the window actually shows, and then I get problems, aero theme gets disabled, which I guess is related to dwm. No login screen though.

Good luck

Edit: English.

[lexikos]

For you on Windows 7?

When I say it doesn't cause any problems on my Windows 7 VM, I mean it doesn't cause any problems on my Windows 7 VM. The window shows, it is the size requested, and Aero continues working.

[Helgef]

For you on Windows 7?

Yes, Aero theme got turned off, it happened twice, and I rebooted after the first time, because my computer had been on for several week. However, I don't think I have updated ahk on that computer, I'll have to check what version I have.

[Helgef]

On win7, ahk 1.1.24.02 64bit unicode, running this code:

Code: Select all

Gui, Show, w16383 h16383

consistently gives me a traytip, saying that the "color scheme has changed to windows 7 basic" (translated from my lang.), and aero theme gets disabled. The gui shows. No other issues.
If I add

Code: Select all

Gui, -caption

above the Gui, show, the theme doesn't change, no traytip.

Just for fun I tested this "anomaly" on my 98SE under AHK Basic.
With size set to max 32742x32742 the window shows, everything else works perfectly.
With sizes larger than that up to 32767x32767 the window briefly shows (if at all) then dissapears and there's only the taskbar button advertising its presence. Everything else works correctly.
In either case there's only an ~2MB memory drop (size of AHK exe).

Told ya 9x rocks!
Just kidding. But the test is real and accurate nonetheless.

(fixed minor typo)

[simplysunny]

Really? I haven't even upgraded to Windows 10 yet... (still 7), but this is a little worrying.

[lmstearn]

Very interesting. Here on 1709 (AMD) everything freezes - CTR-Alt-Del to escape. Once Task Mgr is invoked, it's as if nothing happened. Absolutely nothing in the logs.
