[Windows] Window sometimes rescales itself beyond its border when running other fullscreen apps

[silvernull]

Tauon v7.7.2
Windows 10
Nvidia 552.22

The window image has rescaled itself to a smaller size but all of the buttons are in their usual locations (e.g. X to close window is still in the top right of window).

I don't have steps to recreate, I disabled my monitor a few times and had the window minimized for many hours, as well as opening, closing and ALT TABbing an unrelated Borderless window multiple times.
Along with switching to desktop view a few times, nothing in the Tauon application.

I keep managing to cause this issue and it seems to be relating to 552.22 and rainbow six siege's borderless fullscreen implementation.

I can confirm that the NVIDIA driver does not seem to matter.

It has still been occuring in 7.8.0

[silvernull]

Ok I think it's due to changing resolution on a fullscreen window.
I'm going to test it and see if it happens every time.

[silvernull]

Got it to happen again.
It seems to occur after being in a fullscreen application for an indeterminate amount of time with tauon open on the desktop.

So this is 7.9.0 on Windows?

Is Tauon itself fullscreened when it happens? Got an example of apps you got it to trigger with except for Rainbow Six?

You got multiple monitors?

Could you grab the log from when it happens? Pressing ` or going into Misc to Toggle Console should give last 50 logs.

[silvernull]

Yes

No, but it persists between windowed and fullscreen, don't think so.

No

With difficulty, can't copy it

[silvernull]

I cannot leave fullscreen by pressing alt+enter or f11 either

Persists with it being in tray.

[silvernull]

Unrelated to the window decorations.

This is happening far too often.

[silvernull]

This time, not sure if anything different has occured, also unsure if tauon did the bug before or after r6 was closed,
the GUI and hitboxes lineup.

You should be able to spam the COPY button and it'll work eventually, it does seem mildly wonky for me on Wayland.

I'll probably add an optional log file at some point to help track things down, as on Windows it's effectively impossible to get any logs through the terminal and the console is currently the only way.

Looks as if something triggers goto_album(), and at a later point get_blur_im() hits and some path which triggers this:

		if (oy_size * ratio) - ((oy_size * ratio) // 4) < window_size[1]:
			logging.info("Adjust bg vertical")
			ratio = window_size[1] / (oy_size - (oy_size // 4))
			ratio += 0.2

		new_x = round(ox_size * ratio)
		new_y = round(oy_size * ratio)

		im = im.resize((new_x, new_y))

Looks possibly related to album art for the background?

This could be a red herring and I could be completely off.
