[?] [2398] AIMP lags when Scale Factor <> 100%

[user167842]

I have been using AIMP for about 3 years. About a year ago it started to load (open), maximize, minimize, using/clicking seek bar and load (play) files slowly, like computer was old or slow.

At first, I thought there was a bad setting in the INI configuration file, so I uninstalled and then reinstalled a new, fresh AIMP. With the DEFAULT settings, I loaded all my files and it was very fast, very responsive. But then, I put all the same settings like the old installation and it became slow again, I knew a specific setting was causing this.

Using AIMP on a Ryzen 5, 8GB, SSD machine, connected to 4K TV via HDMI (4k resolution, only tv displayed).

--------------------------------------

SETTINGS THAT CAUSE PROBLEMS (I always have latest version of AIMP)

Layout: Standard
Theme: Dark (also windows in dark mode)
Apply accent color to bottom bar: YES
Apply accent color to window frame: YES
Round window corners: OFF


PREFERENCES > INTERFACE > GENERAL
Night mode: Automatically
Scale Factor: 225%
Text size: 100%
Color schema (automatically): OFF

PREFERENCES > INTERFACE > SKINS
Everything OFF except "Show waveform of playing file over the seek bar"

PREFERENCES > INTERFACE > VISUALIZATION
Everything OFF

--------------------------------------

If "Allow per-pixel semi-transparency" was ENABLED, AIMP opened/loaded about 50% faster, but still slow when using it.

Then I also put Scale Factor to 100%/96dpi and everything was very small, but AIMP now was very fast! Everything was normal, very fast and responsive.

Because everything was very small, I tried something different to make AIMP icons and text to be bigger:
Right-click AIMP.exe > Compatibility > Change high DPI settings > High DPI scaling override > Override High DPI scaling behavior. Scaling performed by: ENABLED (SYSTEM)

Now AIMP is bigger, good size for TV and works fast. Text is a bit pixelated but it is OK, it looks OK.

What is app version?
What skin is used?

Hi Artem,

AIMP version is 5.03, build 2398. Skin is the Default (Standard Layout), dark mode. I've had this problem for about 1 year, so it affected some older versions too.

I will try to isolate the problem (try without TV connected, etc.) to get more information, if you need me to try something specific, I am more than happy to help.

What sound output settings are used?

[user167842]

Sound output is HDMI.





NOTE: When I changed the Windows DPI settings for AIMP.exe to fix the small font, I noticed the same problem that user Kessi11 mentions here https://www.aimp.ru/forum/index.php?topic=69279.0 When AIMP is maximized, clicking the TOP-RIGHT corner of the screen doesn't close AIMP (it doesn't click the "X"), it clicks whatever is behind AIMP. TOP-LEFT corner of AIMP works OK.

DPI settings for AIMP.exe


Mouse is at TOP-LEFT CORNER (I click here and it shows menu)


Mouse is at TOP-RIGHT CORNER (I click here and it clicks the background, AIMP hides, it doesn't close)

Why? AIMP has built-in high dpi support!

Why? AIMP has built-in high dpi support!

Yes, but if Scale Factor is different than 100%/96dpi, it causes AIMP to be slow, sluggish. I will record screen to show you.

Even with default skin?

And yes, problem happens with default skin.

As I see, even in 100% it works not so fast...
