-sdl window intermittently scales instead of resizing
-
-Binary package hint: qemu-kvm
-
-Normally, the SDL output window for a VM resizes to match the VM's resolution. However, intermittently the output is instead scaled within the window. I can't seem to find any pattern to when the output is scaled versus when the window is resized. I would prefer that the window be resized as needed to display the VM in a 1:1 manner.

-Anthony, can you explain the behavior here?
-
-At the very least, we should be able to get something into the documentation.
-
-On Karmic (qemu-kvm-0.11) I noticed some strange behavior. If I physically "moved" the window before X was fully up in the guest, the image would be scaled in a strange way.
-
-I do not see this behavior in Lucid's qemu-kvm 0.12.3. Jamin, do you?
-
-If you accidentally resize the window (even by 1-pixel), then it will stay in scaled mode even during guest geometry changes.
-
-It sucks from a usability perspective. Clever suggestions about how we can support scaling in a more friendly way are certainly appreciated.
-
-@Dustin,
-I've experienced the problem with a rebuild of the lucid package for karmic. The package is in my PPA, https://launchpad.net/~jcollins/+archive/jaminppa.
-
-@Anthony,
-I can assure you that I've seen the scaling without resizing the client window in any way. Simply starting the VM and leaving it untouched periodically results in a scaled display.

-Jamin-
-
-What about 'moving' the client window? I have not seen it rescale at
-random, but I have seen it rescale if I move the window before X comes
-up.
-
-I frequently relocate my VM displays. My host system's window manager is openbox. Normally, for moving any window about my screen, I utilize the ALT+left-click feature to drag the window about. This has the added benefit of ensuring I don't accidentally resize the window.
-
-Most of my guests are Windows based at the moment. When the display scales it tends to remain the size of the booting splash screen.
-
-I just tried some different methods of starting the VMs and dragging the displays about. If I'm performing an ALT+left-click drag when the display wants to resize it seems to switch to scaling instead. So, this may be part of it, but I am very certain I've seen the same result when simply starting the VM and not touching the display in any way.
-
-Just had it happen again. Simply started the VM, didn't touch the SDL window for it at all, guest wound up scaled. Here's the xwininfo output for the SDL window:

-You can disable scaling by hitting ctrl-alt-u.
-
-What's probably happening is that the window manager is generating an extraneous scaling event. I'm going to move this to wishlist as we should provide better user controls of this behavior.
-
-My window manager maximizes all windows. I am running kvm 0.14.
-
-Initially the VM is displayed 1:1 in the top left corner leaving large portion of the window black. Resizing the window or rebooting the VM causes the output to be scaled which is horrendous.
-
-There are three issues here: there is no way to force the window to be the size of the VM output nor is there a way to display the VM output 1:1 regardless of window size nor is there any possibility to make the VM output scale proportionally.
-
-Pressing Ctrl+Alt+u definitely does not disable scaling for me although it causes the VM output to disappear momentarily causing the window to flash.
-
-I guess setting window size can be achieved with some WM hint (and should be a command line option and possibly a option configurable from the monitor). Obviously, not all outputs can set the hint and not all WMs will respect it. However, setting the hint *and* resizing to the desired size should give the correct size in most cases. http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#NORESIZE
-
-The other issue is that scaling does not respect aspect ratio leading to horrendous VM output. I don't think there is any use case for non-proportional scaling.
-
-
-
-I have the same problem too. Anything other than each guest pixel mapping to exactly one host pixel looks bad. There should be a way to ensure that this is always the case (in fact, perhaps it should be the default and there should be a command line switch to allow the possibility of the display being scaled).
-
-VirtualBox gets this right.
-
-This may be the root cause of bug 986192
-
-I have attached a screenshot that shows the *contents* of a SDL window *not* being scaled despite the window being maximized. Is this the same issue or not? If not, can you attach a screenshot describing the issue?

-I guess not. That bug is TwinView specific but this issue happens with
-any graphics.
-
-In fact, in qemu 1.5 this issue is no longer present.
-
-
-As requested here's a screenshot of the scaled window. The expected behavior is that the window be resized to the dimensions of the guest.
-
-Pressing Ctrl+Alt+u within this window corrects the issue and the window is in fact resized to the guest dimensions.
-
-Scaling can be triggered by:
-
-- Pressing ctrl-alt-{minus,plus} (on certain keyboard layouts)
-- a SDL_VIDEORESIZE event
-
-SDL_VIDEORESIZE is always sent on an X ConfigureNotify event when a SDL_VideoSurface is active. (SDL_VideoSurface is NULL if a resize was done in SDL_SetVideoMode).
-
-So it really must be a window manager or something sending this resize event. What WM are you using?
-
-Notes, SDL_VIDEORESIZE (and other events) may be eaten:
-- in the very early start-up stage[1] (causing the issue mentioned in comment 13)
-- during switches to and from fullscreen
-- (some other paths that do not affect QEMU)

-
-Window manager varies. In the original report it was openbox (as I believe I stated, in comment #7). Current window manager is xfwm4. For the screenshot provided, I intentionally moved the window with Alt+left_click as I knew this would trigger the issue (also indicated in comment #7). However, as stated before, the issue happens seemingly randomly on its own without moving the window or interacting with it in any way.
-
-I cannot reproduce with KWin FWIW, but have an openbox box somewhere (no pun intended).
-
-Can you apply the attached debug patch, reproduce your bug (move with alt+click) and attach the output? If the log grows too large, try:
-
- uniq -f1 -c log
-What version of SDL are you using?
-
-Since support for SDL 1.2 has been removed from QEMU now, can you still reproduce this issue with the latest version of QEMU and SDL2 ?
