Added travel channel app. Both my tcl tv and express streamer are having the same issue with it. The screen keeps flickering and even scrolling on its own at times.
all other apps work fine. Per another topic, I tried changing refresh rate option but it didn’t work. Deleted the app and reinstalled. This seems to have fixed on the tv but not the streamer, although I am not certain it was the actual fix on the tv.
the issue does not occur while actually watching content.
Did you restart your Roku device before re-installing the channel? That step is crucial when performing troubleshooting. If you haven't tried the suggested order (remove > restart > re-install), we would recommend giving it a shot once again. We also suggest doing the restart from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
@RokuKariza-D I did as you suggested and problem persists. I even did a reset in place of the power option.
I found that if I change the display to 720p, the app flickers once on its home screen and then it is fine. The TV is 1080p and have no desire in viewing in 720p or switching back and forth when using other apps.
my TCL also flickers once on the app’s home screen, but has no display options and is 1080p.
If the issue persists from one channel after attempting the suggestions above, videos from other channels play fine, contact the channel provider's customer support team to report the issue and get help.
Channels on Roku are maintained by the channel developer themselves. In this case, there's likely an issue within that specific channel that needs to be addressed with an update from them.
