[Bug]: Red and blue color channels swapped on build #523 on Exynos

[lengors]

Problem description

I own a Galaxy S22+ with an Exynos CPU and with build #523 from 20231006 (last successful build from master branch) referent to commit 84901c2, the red and blue color channels seem to be swapped (red colors become blue and vice-versa, other tones of colors like dark blue-purple ish becomes orange, etc). With the build previous to that one though, there are no issues (#522 from 20231002 referent to commit 4acf4b2).

Some notes:

• I'm using the -legacy-drawing flag as without it I get a black screen (this is true independently of which build I choose)
• I have only tested with proot (both on debian and archlinux) using xfce4, but not with termux session or other desktop environment
• I know there's a recent build from 5/6 days ago, but it's from a dependabot branch and not master, so I haven't tried that one

What steps will reproduce the bug?

• Install termux app
• Install termux-x11 app
• Install x11-repo and the termux-x11 deb package referent to the given termux-x11 app (from termux-companion packages)
• Give appropriates permissions to apps and setup termux.properties
• Install debian (or archlinux) proot with proot-distro
• Install xfce4 desktop environment inside proot
• Open termux-x11 app
• Initialize termux-x11 with command: termux-x11 :0 -legacy-drawing
• Start xfce4 session inside proot with env DISPLAY=:0 dbus-launch --exit-with-session startxfce4
• Background should have a dark blue-purple ish tint to it, but has orange which indicates red-blue channels are swapped (another way to see this is by going to youtube, duckduckgo or some other website and see the logos have the wrong colors, same with video, thumbnails, what else)

What is the expected behavior?

Red and blue color channels should be swapped as to give the correct color on, well, anything really.

Does it work fine with termux's own xfce4? Post screenshots.

Does it work fine with termux's own xfce4? Post screenshots.

No, it also has the same issue (just tested).

Here's a screenshot of what the behavior is (Build #523):


And here's a screenshot of what the behavior should be (Build #522):

From both builds or just the one that doesn't work?

Yep ... I'm also having this issue .

Also on an S22

[arenddeboer]

Confirmed on S22 Ultra (Exynos)

[arenddeboer]

I've been playing with the source, bumped the SDK, changed some code and somehow got the color swap issue fixed. The problem is, I'm not sure what made the difference. I'm also a total greenhorn in this domain. Will report back if I have more details.

@arenddeboer

hello. I am a S24+ Exynos2400 model user.

Even on S24+ As with the S22 series Exynos2200 model, there is an issue where the X server color is displayed strangely.

if Please share the APK with the modified contents reflected. Could you please reflect the modified code details in Git?

[arenddeboer]

@hansm629 I wish I could just send a pr with the changes, but a quick diff didn't give me anything to work with. This is a link to the latest Termux X11 APK that I currently use: https://drive.google.com/file/d/1WOb2T3PUpCzMvwsIq9EOP8D6kMQOS0S1/view?usp=drivesdk Let me know if it works for you.

[hansm629]

@arenddeboer

thank you! :)

Thanks for solving it! XFCE4 colors on PRoot-Distro Debian on S24+ Exynos2400 display well!

ah! I have one question. How is the GPU performance in PRoot-Distro of Exynos2200 Xclipse 920?

Exynos2400 Xclipse 940 virglrenderer-android environment and mesa-zink + virglrenderer-mesa-zink + vulkan-loader-android environment

Both show the worst performance and compatibility.

virglrenderer-android has glmark2 performance of about 70~80fps. There is an issue where the texture color appears black. supertuxkart was completely unplayable with a purple screen appearing.

mesa-zink + virglrenderer-mesa-zink + vulkan-loader-androidhad a performance of about 60~66fps and glmark2 was impossible to complete, and supertuxkart entered the game screen, but the UI was broken and the game map and characters were not displayed. So it was impossible to play.

For Exynos2200 Xclipse 920 When combining mesa-zink + virglrenderer-mesa-zink + vulkan-loader-android I heard rumors that it shows good performance and compatibility.

[arenddeboer]

Glad it works for you too! To be honest I haven't experimented much with render options. But proot is indeed very slow and I try to use native XFCE4 where possible.

[whjou]

I'm using S24, have the same issue.

https://drive.google.com/file/d/1WOb2T3PUpCzMvwsIq9EOP8D6kMQOS0S1/view?usp=drivesdk didn't seem to resolve it. I'm using native XFCE4.

For comparison, top half shows a photo in GIMP using tigervnc server & MultiVNC client (expected colours), bottom half shows the same using termux-X11 (unexpected colours).

[hansm629]

@whjou

This is PRoot-Distro Debian Sid installed on Galaxy S24+ (SM-S926N).

I have XFCE4 session colors displayed correctly in the APK shared above.

[whjou]

@arenddeboer @hansm629 Turned out I wasn't testing properly. On retesting https://drive.google.com/file/d/1WOb2T3PUpCzMvwsIq9EOP8D6kMQOS0S1/view?usp=drivesdk it worked after all.

Using https://github.com/termux/termux-x11/releases/download/nightly/app-universal-debug.apk for native, proot-distro debian & proot-distro ubuntu:

After https://github.com/termux/termux-x11/commit/6fcf1b7961f18d909ecedea037bff3cda6156472 you can use -force-bgra option to make it swap colours.

[whjou]

@twaik thanks for the fix. Just a minor comment that the README.md line 59 mentioned the wrong flag. It should be

For some reason some devices show screen with swapped colours, in this case you should pass -force-bgra option.

[twaik]

Are you looking at readme of master branch or the readme of commit itself?

[whjou]

Apologies I looked at the commit at https://github.com/termux/termux-x11/commit/6fcf1b7961f18d909ecedea037bff3cda6156472.

Noted the main page at https://github.com/termux/termux-x11/ is showing correct option.

[twaik]

@lengors @sfantu @arenddeboer @hansm629 @whjou can you please confirm problem existing on the latest build? With -legacy-drawing/-force-bgra and without them?

[arenddeboer]

@twaik When I install the latest build from https://github.com/termux/termux-x11/releases, -force-bgra only doesn't work for me, but -legacy-drawing shows the colors correctly. Without needing -force-bgra. Or am I doing something wrong, I was expecting to need the option -force-bgra for the colors to show up correctly.

[twaik]

@arenddeboer does it work without flags -legacy-drawing? I added one check to enable legacy drawing method automatically but I can not test it on my devices.

[arenddeboer]

@twaik -legacy-drawing is still required. I get a black screen without.

[twaik]

Ok, so that means texture format is fine, but drawing it on actual surface with shaders is problematic. I'll check what can be done.

• https://github.com/termux/termux-x11/actions/runs/7964543153 didn't work for me. Thought it was just me.
• https://github.com/termux/termux-x11/actions/runs/7988796698 worked with -legacy-drawing flag. Explicitly stating -force-bgra flag is not required.

[sfantu]

Working here ... with -legacy-drawing ... haven't test without yet.

[twaik]

I fixed one little thing so termux may work on Exynos without -legacy-drawing. Check build 594. I am waiting for your confirmations.

[whjou]

Tested, it works on my Samsung Galaxy S24 without the -legacy-drawing flag. I'm keeping this build. Thanks!
