6.4.0: Frequent write operations to ReShade.ini if ReShade UI is open in-game

On 6.3.3, file writes to reshade.ini are quite predictable. In-game, when I transition to a new preset, there's a save operation; each color bar in the Process Monitor screenshot belor represents a file access from the game (I'm assuming to save
(Please ignore the first color marker, it was wrongly placed for Explorer.EXE.)

On 6.4.0, though, ReShade.ini is accessed frequently as long as the ReShade UI is shown in-game:

I don't know if this an intended behavior, but it popped up as I was investigating a reported issue from another ReShade user that updated to 6.4.0; they reported that the Global Alpha value was being overwritten every time a new preset was loaded, with the value decreasing each time (the UI turning more and more transparent.) I wasn't able to reproduce the issue, but noticed this while doing root-cause investigation.

Thanks for your attention on this!

(Seems I made a major mess now only with formatting but also my attachments. Please see the listed github.com URLs for the mentioned screenshots.)

The alpha issue is a bug caused by having updated imgui (which changed behavior under the hood unfortunately), it's fixed by github.com/crosire/reshade/commit/7b671f...1a210113eb623d32c300 .

Frequent filesystem access when the overlay is open shouldn't be new in 6.4, but it should be much improved now with github.com/crosire/reshade/commit/07b868...486db4bf77cc7beae0d5 .

Awesome, thanks for the quick reply and your work on these issues!

I came here specifically for this issue. I had uninstalled Reshade too often in the span of the last 2 days and I couldn't figure out what was causing this insane bug and it drove me wild.

I could replicate this in FFXIV when using shaders that mess with alpha transparency settings and it would eventually drop the value to 0.0 which would make it completely disappear. I've gone around this by keeping a backup copy of Reshade.ini file but I'm glad someone else picked up on this and it got fixed!

how do we install these fixes? i tried doing it with powershell but i just kept getting errors

Update to 6.4.1.

I updated to 6.4.1 and it still didnt fix the transparent issue.

It does, but it doesn't reset whatever global alpha value you have now set in your config, that you have to change yourself (ReShade.ini "[STYLE] Alpha=1.0").
