Touch Display goes partly grey on Sudoku only

notonyourtintype · 08-27-2017, 01:17 PM

Hi folks,
Have a Kobo Touch, updated to the latest firmware on 5/16/17 ( 4.4.9344 (6f70079280). Everything working fine except two things: Sketchpad and Sudoku, both betas, which now have weird display issues.

Sudoku: Game comes up normally, but as soon as you touch any game button on the screen, a grey zone blots out the last 2 rows of cells and part of the screen down to the number-choice buttons. See attached jpg. The only way to play the game in that last row of 3x3 cells is to remember what's there, plunk a finger on a cell to set it, then NEW GAME, CONTINUE PLAYING, which repaints the screen. Repeat.

SKETCHPAD: brings up a half-cleared screen (faded icons of the book covers from home page), but lets you draw. Hit SAVE, the background goes blank. Hit Exit, and it plops a black square onto the lower left hand corner of the book thumbnails on the Home page. Tapping or holding on it takes you to LIBRARY, where the Sketchpad entry is first (in Recent order), shows as a solid black block with a bit of pale in it. Opening it opens the drawing, but... no buttons to exit it with.

We have a second Touch, firmware not updated since 2/11/2014 (3.2.0), and like its sister, both have been dropped a few times. But... the un-updated one works just fine.

No other display anomalies in the new firmware Touch.

I've popped the back open on the one with the display problems, popped the display interface and battery cables off and reseated them, checked for anything obvious, but... there we are.

Any ideas (short of "buy something new") would be welcome!

Thanks,
Mike

Reinstall Sketch and Sudoko

I sense this is the same screen corruption bug I see on the Touch with WiFi syncs. Nothing we can do; we need Kobo to fix it

I've just tried Sudoku on my Touch and am seeing screen corruption across the same area. This is looks the same as the problem PeterT is referring to. Hopefully Kobo will be able to fix it. In the meantime, if it is a problem for you, I would recommend going back to the 3.19.x firmware.

My Kobo Touch is on the same FW version as yours and I do not see this problem. What difference might there be between our devices? My Touch is a C-model, and I have installed the complete FW (not only the KoboRoot.tgz).

Same here.

I do not see this. The background remains as it was in the beginning with faded icons, book titles and so on.

I am not sure what your are talking about. What buttons to exit? When you touch the screen, is there no "< books" on the bottom menu bar? Or can you not open the main menu and go to home or library?

Good point. The Touch I see the problem on is an N905. It has the full install of the firmware I am using. I've been seeing problems like this since the change to 32bpp. The N905C is slightly different hardware, so it might only be affecting the N905 and N905B.

Yep. Mine is also the n905
