Re: [PATCH v7] ui/cocoa: Use NSWindow's ability to resize

[Marek Glogowski]

Hi

For me, the problem does not occur if you use the maximum screen resolution available.

For me it is 1680x1050 - everything works fine.

When I change the screen preference to a smaller screen resolution than my maximum (1440x900,1024x768 ...) the mouse starts to malfunction. The mouse pointer works strenuously and with a delay.

Checked on the current version with git qemu-system-ppc AOS4 with V8 and V7 patch and the older version qemu-system-aarch64 Linux/Fedora

This patch now works with the "option zoom-to-fit=on/off"

thank you very much.

But there is severe mouse lag within Cocoa output in full screen. You

can reproduce the problem by using the mouse very slowly inside the machine
where the mouse pointer no longer moves (guest). This issue only occurs with
Cocoa edition SDL/GTK works without mouse lag within the machine.

I can't reproduce the issue. Is it a regression caused by this change or

an existing bug?

I'm not sure how to reproduce it, but when I compile Qemu from master source, zoom-to-fit for cocoa output is always active without using your patch and cannot be enabled or disabled in full screen. Here the mouse speed is about the same as under the MacOs host system.
When using their latest patch series v8 for cocoa I can enable and disable zoom-to-fit with "-display cocoa,zoom-to-fit=on/off -full-screen" but the mouse speed then becomes slower. I'm not sure what changes there were from Qemu Master where part of their patch must be included, unless someone else has added something similar for Qemu Master.

Can you tell me your whole command line and guest operating system?
